Question

In the nucleus, a sodium atom (Na) has 11p+ and 12 nºo. How would you write the

sodium ion based on the loss of one electron?

Answer 1

Na⁺

Step-by-step explanation:

Given parameters:

Number of protons = 11

Number of neutrons = 12

Writing the expression based on sodium ion that lost one electron;

In a neutral sodium atom, the number of protons and electrons are the same. Number of protons are the the positively charged particles in an atom.

Number of electrons are the negatively charged particles.

If an atom loses electron for instance sodium:

Number of electrons = 10

Number of protons = 11

Charge on the atom = 11 - 10 = 1+

So, the symbol of the atom is Na⁺
