An atom has an atomic number of 13 and a mass number of 27. It also has a +3 charge. What do you know about this atom?
|
|
it formed an ionic bond
|
|
|
it formed a covalent bond
|
|
|
it is neutral
|
|
|
it does not have neutrons

Explanation:
Detailed explanation-1: -of neutrons = 27-13 = 14. And neutrons are=27-13 = 14. Hence, we can conclude that number of electrons, protons and neutrons in the ion formed is 10, 13, 14 . The ion can be represented as: Al3+ and its valency is +3.
Detailed explanation-2: -therefore n= 27-13 = 14 = number of neutrons.
