Answer 1

The question is incomplete.

Correct Question:

The tendency of an element to lose an electron is called:

1. Electronegativity
2. Non-metallic character
3. Electropositive character
4. Electron affinity

Answer:

The tendency of an element to lose an electron is called the Electropositive character.

Explanation:

As an element loses an electron(s), it becomes positive in nature. For e.g., sodium (¹¹Na) loses one electron to attain a stable gas configuration (resembling Neon (¹⁰Ne)).
¹¹Na ↔ ¹⁰Na + e⁻

This character of an element to lose an electron is known as an electropositive character or metallic character.
As we go from left to right along a period, the metallic character decreases and vice-versa; and,
As we move down a group, the electro positivity increases.

The metals have a higher tendency to lose electrons and the non-metals have a tendency to accept electrons (electron affinity).
