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?

Respuesta :

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

The number of proton, electron and neutron is 119, 119 and 183 respectively.

We were given an element to have A= 302 and Z= 1119. The mass number of an element is always more than the atomic number which means A is the

mass number which is 302 and atomic number is A which is 119.

Mass number (A) = 302

Atomic number (Z) = 119

Atomic number is the amount of proton in an element.

Proton = atomic number = 119

Since it's a neutral atom , then proton= electron

Electron = proton = 119

Mass number = proton + Neutron

Neutron = Mass number — proton

Neutron = 302 — 119

Neutron = 183
