Question

The ion of an element has 3 positive charge 27 mass number and 14 nuetrons

Answer 1

Let the element be 'x'.

We know that:

Mass number = Number of neutrons + Number of protons ....(1)

In this question, it is given that:

Mass number of x = 27; Number of neutrons in x = 14

Putting these values in (1), we get:

27 = 14 + Number of protons in x

Number of protons in x = 27-14 = 13
