Question

Imagine that you helped to discover a new element:

A= 302; Z = 119. How many protons, electrons, and
neutrons are in each atom of this element?

Answer 1

Proton = 119

Electron = 119

Neutron = 183

Step-by-step explanation:

Mass number (A) = 302

Atomic number (Z) = 119

Proton = atomic number = 119

Since there is no charge on the element, it means the element is neutral.

Therefore,

Electron = proton = 119

Mass number = proton + Neutron

Neutron = Mass number — proton

Neutron = 302 — 119

Neutron = 183
