When a mercury-202 nucleus is bombarded with a neutron, a proton is ejected. what element is formed?

That will make a gold-202 nucleus.

Refer to a periodic table. The atomic number of mercury Hg is 80.

Step One: Bombard the with a neutron . The neutron will add 1 to the mass number 202 of . However, the atomic number will stay the same.

.

Double check the equation:

Step Two: The nucleus loses a proton . Both the mass number 203 and the atomic number will decrease by 1.

Refer to a periodic table. What's the element with atomic number 79? Gold Au.

.

Double check the equation:

A gold-202 nucleus is formed.

answer; i believe the correct answer is (c) /// is a homogeneous mixture of gaseous substance nitrogen,oxygen and smaller amounts of other substancesmixtures can be either ( homogeneous or heterogeneous)plz check first good luck
