yes
elements from group1-2 ,13-18 are called representative elements. Those from 3-12 form the transition elements!
the group1 elements
-melting/freezing point -boiling point -density -reactivity with acid -flammability -solubility
Hydrogen, Lithium, and Potassium
Alkali Metals
Oh honey, the Representative Elements are just the main group elements on the periodic table. They're the popular kids at the chemistry party, hanging out in groups 1, 2, and 13-18. They're the ones who aren't trying too hard to be cool, just doing their thing and bonding with other elements to form compounds.
Group I elements are called alkali metals as they are generally basic in nature
Elements are pure substances inwhich all the atoms have the same number of protons (same atomic number) and thus have the same chemical properties. They cannot be separated by normal chemical means into any simpler substances.

No, 3-12 elements on the periodic table (group 3 to group 12) are transition metals, not representative elements. Representative elements are found in groups 1 and 2, and 13 to 18 on the periodic table.
Sodium, Na, is in group 1 on the periodic table. The elements in group1 are the elements in that vertical column, which are Li,Na,K,Rb,Cs,Fr.
