Isotopes of a given element have the same number of protons but different numbers of neutrons in each atom
The number of protons in an atom is also known as the:
atomic number
The number of protons and neutrons in the nucleus of the atom is known as the:
mass number
Silver has two isotopes: Ag-107 and Ag-109. Their respective % abundances are 51.8% and 48.2%. Calculate the relative atomic mass of silver.

Why are atoms electrically neutral?
# positively charged particles (protons) = # negatively charged particles (electrons)
State the relationship between wavelength, frequency and energy
the longer the wavelength, the smaller the frequency, the smaller the energy
Energy is ____ when an electron moves from lower to higher energy level.
absorbed
Energy is ____ when an electron moves from higher to lower energy level.
released
Why do elements in group 8 not form compounds?
They already have full outermost shell of electrons
What does the octet rule state?
The octet rule says that atoms are very stable when they have 8 electrons in their outer shell.
