Imagine that you helped to discover a new element; A=302;Z=119. How many protons, electrons, and neutrons are in each atom it this element?

Sagot :

Explanation:

Given that,

Mass number, A = 302

Atomic number, Z = 119

We know that, atomic number = no of protons

Protons = 119

Mass no. = No. of neutrons + No. of protons

302 = No. of neutrons + 119

No. of neutrons = 302 - 119

= 183

No. of electrons = No. of protons

= 119
