When electrons are removed from an atom, the atom becomes positively charged and is referred to as a(n)

Explanation:

When an electron is removed from an atom then the atom acquires a positive charge.

Therefore, it results in the formation of a cation.

For example, calcium has atomic number 20 and its electronic distribution is 2, 8, 8, 2.

Therefore, it loses two electrons and changes into ion. Hence, a neutral atom of calcium changes into cation.

Thus, we can conclude that when electrons are removed from an atom, the atom becomes positively charged and is referred to as a cation.

the answer would be a

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