Question

in electron capture, what happens to the atomic number? *
it remains unchanged
it decreases by 1
it increases by 1
it doubles
what is gamma (y) radiation primarily characterized by? *
particle emission
atomic number transformation
mass change
energy release

Explanation:

In electron - capture, a proton in the nucleus combines with an inner - shell electron to form a neutron. Since the number of protons (which determines the atomic number) decreases by 1, the atomic number decreases by 1. Gamma radiation is a form of electromagnetic radiation and is primarily characterized by the release of energy in the form of high - energy photons without any change in atomic number or mass number and without particle emission in the traditional sense like alpha or beta particles.

Answer:

1. B. It decreases by 1
2. D. Energy release
