Question

Imagine that you helped to discover a new element:

Answer 1

Answer:

Proton = 119

Electron = 119

Neutron = 183

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

Answer 2

A is the mass number which is the sum of protons and neutrons of an atom
Z is the atomic number which is the number of protons
A=302 (protons+neutrons)
Z=119 protons
Neutrons=302-119=183
Therefore Protons 119, electrons 119, neutrons=183
