A chemical element is a substance that cannot be broken down by chemical means and is composed of only one kind of atom. A chemical element is a chemical substance consisting of a single type of an atom distinguished by its atomic number. The atomic number represents the number of protons contained in the atom.

chlorine, gold, potassium, calcium, etc. Can be found on Periodic Table.

∙ 7y agoElements are substances made up of only one type of atom. This means that they consist of atoms all with the same number of protons. The number of neutrons, however, can vary within an element; this is called isomerism.

∙ 16y agoIf you are asking what an element is, it is a pure substance that can't be broken down by physical or chemical means. hope that helps! : )

It's also considered a pure substance which is the same as what was previously answered

Boron family is group IIIA so 3 electrons are in the outermost shell.
Why do the dust particles move when a beam of sunlight enter the room?
The random motion of small particles in the air is called Brownian motion (named after the botanist Robert Brown). This motion is caused by the collisions of the particles with the molecules of the gases making up the air.
List and define replacement in chemistry?
There are two types of replacements in Chemistry. There are single and double replacements. A single replacement is when an element replaces another element within a compound, but in order for this reaction to occur the elemet that is being replaced must be less active than the element that is being replaced. This can be determined using an activity series. A double replacement is when two compounds switch their elements: NaF + AuCl --> NaCl + AuF. (This reaction may not actually occur, it is just a demonstration of how the elements replace eachother). Finally, within these reactions if pure water (H2O) is formed the reaction is classified as a neutralization and a no reaction. !
What chemicals are contained on the sides of a matchbox?
