Question

Which of the following statements about metal elements is correct?

A. Metals tend to easily gain more valence electrons.
B. Metal elements are always heavier than non-metal elements.
C. Metals tend to easily lose their valence electrons.
D. A metal atom can take an electron from a non-metal atom.​

Answer 1

Answer: C. Metals tend to easily lose their valence electrons.

Step-by-step explanation:

Metals are those substances which have tendency to loose their valence electrons to attain noble gas configuration and forms positive ions called as cations.

Example: Gold, potassium etc

`M\rightarrow M^++e^-`

Non metals are those substances which have tendency to gain valence electrons to attain noble gas configuration and form negative ions called as anions.

Example: Sulphur, Chlorine

`N+e^-\rightarrow N^-`
