A
number of protons and neutrons
13
Q
atomic symbol (middle letter(s)) means
A
which element it is
14
Q
atomic number (bottom number)
A
number of protons (equal to the number of electrons)
15
Q
how do you find a noble gas via the electrons
A
check how many electrons are on the last shell, if there are none or if it is full then it is a noble gas
