Oxygen decays to form nitrogen. 15 8 o → 15 7 n + 0 1 e this type of nuclear decay is called .

decay

Explanation: General representation of an element is given as: where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

:  It is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. This is also known as -decay. In this the mass number remains same.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
