A dotted line indicates that the bond is not a full bond, it is only a partial bond as in a hydrogen bond or a partially formed or broken bond in a transition state. Also, as mrigank pawagi notes in the comments, the dotted line can be used along with the solid line to denote bonds that have partial double bond character due to resonance.

Bonding configurations are readily predicted by valence-shell electron-pair repulsion theory, commonly referred to as vsepr in most introductory chemistry texts. This simple model is based on the fact that electrons repel each other, and that it is reasonable to expect that the bonds and non-bonding valence electron pairs associated with a given atom will prefer to be as far apart as possible.
The chemical symbol, sb, comes from the element's historical name, stibium. Discovery: antimony was a known metal in the 17th century and was likely used even earlier.
The nemeth code defines sign as the printed mark and symbol as the braille representation of that sign. The usual nomenclature for the letter(s) representing the name of a chemical element is chemical symbol.
Lead, a soft, silvery white or grayish metal in group 14 (iva) of the periodic table. Lead is very malleable, ductile, and dense and is a poor conductor of electricity. Known in antiquity and believed by the alchemists to be the oldest of metals, lead is highly durable and resistant to corrosion.

The definitions surveyed in this article encompass up to 96 out of the 118 known chemical elements; only mercury, lead and bismuth meet all of them. Despite this lack of agreement, the term (plural or singular) is widely used in science.
Boron carbide, (b4c), crystalline compound of boron and carbon. It is an extremely hard, synthetically produced material that is used in abrasive and wear-resistant products, in lightweight composite materials, and in control rods for nuclear power generation.
The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number.
We tracked the chemical transformations of pb and sb released during bullet weathering as a function of time and soil properties. During 2014 summer, an amendment of ferrous chloride (fecl) with a calcium carbonate (caco) buffer was added to a subset of the berms of each soil type to test this remediation strategy.
Chemical shells contain just a small explosive charge to burst the shell, and a larger quantity of a chemical agent or riot control agent of some kind, in either liquid, gas or powdered form. In some cases such as the m687 sarin gas shell, the payload is stored as two precursor chemicals which are mixed after the shell is fired.
The oxygen atom and hydrogen atoms form a covalent bond with one another to create stable outer shells of electrons. The electrons are shared unequally resulting in a polar molecule whose slight charges form weak hydrogen bond attractions with other water molecules.
When a bullet fragment is found completely crushed, the comparison of micro-striations is impossible. The only way to compare two bullets is by comparison of their chemical composition. An icp-ms method is able to measure the percentage of antimony, amounts of trace elements and lead isotopic ratios of the bullets.
Incorrect bullet choice can also lead to an excessive bore velocity, causing the bullet to slide over bullet rifling and so resulting in a low spin rate. Types of firearm in the uk, the firearms act 1968 describes a firearm as “a lethal barrelled weapon of any description, from which any shot, bullet or other missile can be discharged”.
Its chemical behaviour shows many similarities with that or silica and zirconium, as an element belonging to the first transition group. Its chemistry in aqueous solution, especially in the lower oxidation states, has some similarities with that of chrome and vanadium.
A typical tracer bullet consists of a gilding metal bullet jacket and a lead core with a base cavity containing the tracer composition. Paper discs and lead, steel, or brass washers sealed with varnish are sometimes used to seal the base of the bullet. Four examples of tracer compositions are69: barium peroxide 86% (oxidant and coloring agent).
The wavy line usually represents either that that part of the molecule is unimportant or that the stereochemistry at that specific position is unimportant (or unknown). The dotted line usually represents intermolecular interactions, like hydrogen bonds. Dashed lines refer mostly to partial bonds such as in the transition state.
Managers in the writing of elements and standards as they prepare performance plans. This material explains how to develop good performance elements and measurable standards. This document contains several job aids, including some examples of generic results-oriented elements and measurable standards.
These tips allow laboratories to maintain effective chemical hygiene plans that will minimize spills, leaks, and potentially harmful chemical exposures.
It is never found as free element in nature, but it is contained in many rare minerals. The main mining areas are cina, usa, brazil, sri lanka, india and australia with reserves expected to exceed one million tonnes. World production of pure gadolinium is about 400 tonnes per year.
In the case of a non- jacketed bullet, the rifling will strip lead from the bullet' s surface, thus dramatically increasing the percentage of non-primer-based airborne lead. The change to a bullet with a copper/zinc jacket extending over the base was a fairly simple matter of reducing the bullet sourced airborne lead, but finding a non-mercuric.
Having already examined the chemical compounds that give fireworks their colours in a previous graphic, i decided to examine another important firework component here: the first chemical explosive, gunpowder, also commonly referred to as black powder. Until the mid-19th century, gunpowder was the only known chemical explosive.
The elements that are to be analyzed must be known in advance. The material is dissolved in a suitable solvent and then introduced into a flame or furnace so that it can be vaporized. For illustration purposes, assume that the chemist is going to determine the amount of lead in a bullet.
It consists of potassium nitrate (75% by weight), charcoal (15% by weight), and sulfur (10% by weight). Each of these components plays an important role in the combustion of gunpowder. Potassium nitrate, also known as ‘saltpetre’, or ‘saltpeter’, decomposes at high temperature to provide oxygen for the reaction.

Tungsten carbide (chemical formula: wc) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives, armor-piercing shells and jewellery.

A description list is a list of terms, with a description of each term. The dl tag defines the description list, the dt tag defines the term (name), and the dd tag describes each term:.
To improve bullet performance and accuracy, the jacketed bullet was developed. This is a family of bullets that use a substantial brass or copper outer shell, usually filled with lead by casting or cold forming, and having several different configurations for specific performance criteria.
Occasionally web developers, editors, and publishers need to quickly copy and paste bullet points, funky fonts, and symbols. Below you will find a large selection of of characters to choose from.
If it has a solid border, it’s a naturally occurring element, whereas if it has a dotted border, it is radioactive, and if it contains dashes, it is a human-made element. A single thick line may appear in the middle of the periodic element in which the left-hand side is for metallic elements, and the right-hand side is for non-metallic elements.
