If two protons and two neutrons are removed from the nucleus of an oxygen-16 atom, a nucleus of which element remains? express your answer as an isotope (e. g., as 31h).

Explanation:

A particle with two protons and two neutrons is a helium nucleus.

Your unbalanced nuclear equation is:

The main point to remember in balancing nuclear equations is that the sums of the superscripts and of the subscripts must be the same on each side of the equation.  

Then

8 = x + 2, so x =  8 - 2 =  6

16 = y + 4, so y = 16 - 4 =12

Element 6 is carbon, so the nuclear equation becomes

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
