Answer 1

heya friend your answer!!!!

I think k+ forms easy cation
option A is correct.

Answer 2

Answer:

The correct answer is option 1

Explanation:

K+

• A cation is a positively charged ion. Cations are positively charged because they have more protons than electrons. Anions are negatively charged and have more electrons than protons.
• Both these elements have 1 electron in their outermost shells which they can lose easily to become K+ and Na+ respectively.
• K+ having a larger atomic radius gives away its electron more easily as a force of attraction on its outermost shell is reduced due to increased distance from the nucleus.

Na+

• Sodium is a cation (Na+). known as a monoatomic cation.
• Because no protons are more than no electrons in sodium.
• Divalent cation-having two electron in outermost shell like Ca++ and Cu++
