Answer 1

Explanation:

The number of protons in the nucleus of an atom is called the atomic number, represented symbolically as Z, and it is a unique characteristic of an element. Only carbon atoms can have 6 protons in the nucleus, and only oxygen atoms have a Z=8, meaning that there are 8 protons in the nucleus of the atom.

.An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across. 

Components: Electrons and a compact nucleus of protons and neutrons

Electric charge: zero (neutral), or ion charge

Mass range: 1.67×10−27 to 4.52×10−25 kg

Diameter range: 62 pm (He) to 520 pm (Cs) (data page
