Atomic number:
• Mass number:
• No. of electrons:
No. of neutrons :
• Valency:​

Answer 1

Answer:

atomic no: 17

atomic mass:35

vale

Answer 2

Answer:

Explanation:

Atomic number:17

Mass number:35

No.of electrons = Atomic number =17

Number of protons =17

Configuration:

1s2 2s2 2p6 3s2 3p5

Thus to complete octet it needs 1 e

Therefore Valency =1
