They're both in Period, or row, 2.
The most familiar metals in groups 13 through 16 in the periodic table are aluminum,tin,and lead.
Sodium, lithium, potassium
it is titanium
The most common plutonium isotope is plutonium 239.
There are 6 noble gases in periodic table. The common one is helium.
The most familiar metals in groups 13 through 16 in the periodic table are aluminum,tin,and lead.
The word famous is not adequate in chemistry.The first group of the periodic table of Mendeleev contain: lithium, sodium, potassium, rubidium, caesium, francium. The most common element in this group is of course sodium.
Lithium generally has a charge of +1.
Lithium is used primarily for batteries. Lithium compounds can also be used in the treatment of bipolar disorder.
Sodium, lithium, potassium
it is titanium
The most common plutonium isotope is plutonium 239.
Generally, in Li-ion (or Lithium ion) batteries.
If you look at the periodic table, Lithium (Li) is in the first column, group 1A, under Hydrogen, and above Sodium (Na). These elements are typically "electron donors" to fill out their electron shell. So, Lithium, Hydrogen, and Sodium all would typically ionize with +1 charges.
There are several possible meanings in the field of Chemistry. I suspect that the most common usage is an abbreviation for "Rare Earth Metal" referring to any element from that group on the periodic table.

The most common halogen on the periodic table would have to be either chlorine or iodine.
