Fill the missing blank i’m generally confused about this so if anyone could help me it would mean a lot

The answers to your questions are given below.

Explanation:

1. The symbol of Zinc is Zn

2. Determination of the proton number

Atomic number is simply defined as the number of protons in the nucleus of an atom. Mathematically, it is expressed:

Atomic number = proton number

Atomic number = 30

Therefore,

Proton number = 30

3. Determination of the neutron number

Mass Number = 65

Proton number = 30

Neutron number =?

Mass number = Proton + Neutron

65 = 30 + Neutron

Collect like terms

65 – 30 = Neutron

35 = Neutron

Thus,

Neutron number = 35

4. Determination of the electron number

Since the element is in it's ground state (i.e it has no charge), thus, the number of protons of the element is the same as number of electrons i.e

Electron number = proton number

Proton number = 30

Thus,

Electron number = 30

a sequence is a function whose domain is the set of natural numbers.

natural numbers are all the negative and positive integers
