An atom has an 16 protons, 18 neutrons, and 13 electrons. what are its atomic number, atomic mass, and net charge?
a) atomic number = 16, atomic mass = 34, net charge = 3+
b) atomic number = 16, atomic mass = 34, net charge = 3−
c) atomic number = 34, atomic mass = 16, net charge = 3+
d) atomic number = 34, atomic mass = 16, net charge = 3−

Atomic number = number of proton = 16

Atomic mass = number of proton + number of neutron = 16+18 = 34

Net charge = Number of proton - number of electron = 16-13 = +3

OPTION A IS YOUR ANSWER

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
