Answer
a. a neutron has about the same mass as a proton
b. neutrons and protons are found in the nucleus
c. electrons are attracted to the protons
d. electrons have a 1- charge
Work Step by Step
to answer this question you must study 'Electrical charges in Atoms' at page 111 and 'Mass of the Atom' at page 113.
Atoms are composed of subatomic particles,two with electrical charges and attracted to each other (protons and electrons).The subatomic particles are protons ( with positive charge 1+ and heavy mass), electrons ( with negative charge 1- and small mass) and neutrons ( with no charge and about the same mass of protons)
Remember, only neutrons and protons can be found inside the nucleus
