Question

What Are Atoms???????????????????????????????????????????????????/

Answer 1

Answer:

Explanation:

An atom is the smallest recognised division of a chemical element and is made up of three particles: the proton, neutron and electron.

99% of the mass of the atom is held in the central nucleus, comprising the protons and neutrons. The negatively charged electrons whip around the nucleus in orbital shells of different energies.

• The number of protons in a nucleus is called its atomic number.
• The number of electrons in an atom is equal to the number of protons - this means that atoms have no overall charge.
• If an atom gains or loses electrons, it is called an ion.

The word Atom comes from the Greek word for 'indivisible' - ironic, seeing as we know atoms are made of even smaller subatomic particles.

Particle            Relative Charge             Relative Mass

Proton               +1                                                 1

Neutron             0                                                   1

Electron           -1                                               1/1836

Answer 2

Answer:
