Any sample of an <em>ELEMENT</em> is made of only one type of atom.
Here are some elements:
-- Hydrogen, Helium, Neon
-- Carbon (lead in a pencil, also diamonds)
-- Oxygen, Nitrogen, Argon (All mixed together in air, but not hooked up with other atoms)
Other elements you may have heard of:
-- Silver, Gold, Copper, Iron, Lead, Aluminum, Silicon, Chlorine, Calcium, Titanium, Nickel, Tin, Platinum, Mercury, Radium, Uranium
As temperature decreases, the steel will contract (volume decreases) thereby, an increase in Density.
When atoms combine to form covalent bonds, the resulting collection of atoms or group of atoms is called a molecule.
<h3>
How does atom combine?</h3>
Atoms can combine with each other through sharing of the electrons, donating the electrons etc. to make molecules.
When atoms combine by forming covalent bonds, the resulting collection of atoms is called a molecule. We can therefore say that a molecule is the simplest unit of a covalent compound.
Thus, when atoms combine to form covalent bonds, the resulting collection of atoms or group of atoms is called a molecule.
