Question

*The positive ion formed after losing an electron in a figure is called _______.*

1️⃣ magnesium ion
2️⃣ oxygen ion
3️⃣ sodium ion
4️⃣ chlorine ion​

Answer 1

Answer:

Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations.

Answer 2

"The positive ion formed after losing an electron in a figure is called cation."

What is cation?

• An atom that is capable of becoming electropositive, tends to lose electrons.
• Every atom desires to complete its octet rule.
• To complete its octet, an atom either gains or lose electrons so that its outermost shell has 8 electrons.
• After losing electrons, the atom has number of protons more than the number of electrons.
• An atom having number of protons more than number of electrons is called cation.
• Magnesium has (2,8,2) as electronic configuration. Here 2 electrons are lost and it becomes a cation.

• Sodium has (2,8,1) as electronic configuration. Here 1 electron is lost and it becomes a cation.
