Question

Amongst the electrons revolving around the nucleus, which electron will determine properties of an element. give reason why​

Answer 1

Answer:

...hey dear here is your answer ❤️...

Explanation:

The valence electrons determines the chemical properties of an element. Valence electrons is the electrons present in the last shell of an atom. The valence electrons determines the valency of an element. ... Hence , the chemical properties depends on the valence electrons.

hope it helps you

Answer 2

Answer:

the electrons in the valence shell(last shell) because...

look at alkali metal they have 1 e- in the valence shell so they have high tendency to loose e-. Halogen-> 7 e- in valence shell so they have high tendency to loose e-. Noble gases... 8 e-. so they are non reactive cauNobellap5ggney have completed the duplet or octet rule

1. electrons in valence shell helps in distinguishing metals , nonmetal and Nobel gases
2. metals have 1,2 or 3 electrons in their valence shells
3. non-metals have 4,5,6or 7 electrons in their valence shells
4. noble gas have 8 electrons in their valence shell
