Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
For sodium to transform from a neutral atom to a positive ion, it must:
A
gain an electron
B
gain a proton.
C
lose an electron.
D
lose a proton.
Explanation: 

Detailed explanation-1: -Neutral atoms can be turned into positively charged ions by removing one or more electrons. A neutral sodium atom, for example, contains 11 protons and 11 electrons. By removing an electron from this atom we get a positively charged Na+ ion that has a net charge of +1.

Detailed explanation-2: -A neutral sodium atom is likely to achieve an octet in its outermost shell by losing its one valence electron. The cation produced in this way, Na+, is called the sodium ion to distinguish it from the element. The outermost shell of the sodium ion is the second electron shell, which has eight electrons in it.

Detailed explanation-3: -Cations. A neutral sodium atom is likely to achieve an octet in its outermost shell by losing its one valence electron. The cation produced in this way, Na+, is called the sodium ion to distinguish it from the element. The outermost shell of the sodium ion is the second electron shell, which has eight electrons in it.
