metals = left, non-metals = right, metalloids on staircase
There is no staircase, there is no spoon
metals on the staircase, nonmetals = right, metalloids = left
metals = left, non-metals = left, metalloids = left
2

Tantalum (Ta)
Sullivanium
Arsenic (As)
Iron (Fe)
3
Group 1 (the alkali metals-- Li, Na, K, Rb, Cs) all react the same because all they have the same number of...
electrons
valence electrons
protons
futons

14
Why does Cobalt come before Nickel on the periodic table even though it has a greater atomic mass than Nickle?
Nickel has 1 more proton than Cobalt
Mendelev didn't like Nickel
It has more electrons than Nickel
Because it was discovered first
