Question

Electron capture by (⁷Be).

a) (⁷Be) undergoes electron capture.
b) (⁷Be) undergoes βᵈecay.
c) (⁷Be) undergoes β⁺ decay.
d) (⁷Be) undergoes α decay.

Answer 1

Electron capture occurs when one of the inner electrons in an atom is captured by the atom's nucleus. In the case of (⁷Be), electron capture would be written as ⁷Be + e− → ⁷Li + Ve.The correct answer is option A.

Step-by-step explanation:

Electron capture occurs when one of the inner electrons in an atom is captured by the atom's nucleus.

This process is denoted by the letters EC and is a nuclear reaction that consumes an electron.

The products of electron capture have less mass than the parent plus the electron. If a nuclide undergoes electron capture, the electron capture equation is AYN+1 + Ve(electron capture, or EC) and Z-1.

In the case of (⁷Be), electron capture would be written as ⁷Be + e− → ⁷Li + Ve.The correct answer is option A.
