Answer:

  1. 53 protons
  2. 131g
  3. Iodine
  4. Halogens

Explanation:

atomic no. = no. of protons

= 53 proton

mass = no. of protons + no. of

neutrons

= 53 + 78

= 131

The element described in the question has a mass number of 131 ; which is the mass number for the element iodine,which belongs to the Halogen group.

Given the Parameters :

  • Number of protons = 53
  • Number of neutron = 78
  • Number of electron = 53

  • Mass number = proton number + neutron number

Mass number = 53 + 78 = 131

According to the periodic table, the element with a mass number of 131 is iodine, Hence, the element is iodine.

According to the periodic table, iodine belong to group 7 which is the halogen group.
