An element produces an ion with a +3 charge. If an isotope of this element has a mass number of 158 and 61 electrons,  what is the identity of the element?

Gd, Gadolinium

300

Boron exists in two isotopes, boron-10 and boron-11. Based on the atomic mass, which isotope should be more abundant?   

The atomic mass of boron is 10.811; therefore, boron-11 is more abundant because the mass number is closer to the atomic mass.
