Question

Explain the term :
Atomic mass,Atomic radius, Atomic number. ​

Answer 1

Answer:

Atomic mass : Atomic mass is roughly equal to the sum of the individual particle masses of an atom. Atoms have three basic components: protons (positively charged particles), neutrons (non-charged particles), and electrons (negatively charged particles).

Atomic radius : The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons

Atomic number :The number of protons in the nucleus of an atom, which is characteristic of a chemical element and determines its place in the periodic table.​

Answer 2

Answer:

Atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number.
