The first group, group IA, contains the alkali metals, but also involves hydrogen, a non-metal. Though hydrogen is physically in the same group, its properties are not representative of the rest of group IA. On some periodic tables, hydrogen will somehow be "split off" from the other elements in the group, indicating that it really doesn't belong.
the lowest ionization energy in IA :hydrogen ,lithiun ,sodium and potassium
Group 1 Metals
In the periodic table of Mendeleev radium is in the second group (alkaline earth metals), period 7, atomic number 88; Ra ia a radioactive element, solid, rare in the nature.
What relationship exists between the electron structure of Group IA ion and the electron structure of the nearest Noble Gas?
The most electrons an outer shell for group IA metals can have is 2 because IA metals are of the s energy level the max they can hold in an orbital is 2 electrons.
Aluminum is the 3 most used element
sodium
The ONLY liquid elements (at STP) areMercury, Hg, in group 12Bromine, Br, in group 17Notations like ia, iia, ib or iib are not commonly in use, maybe in older books or periodic tables.
Group IA or group 1 elements are known as alkali metals.
The element with its outermost electrons in an S sublevel is found in Group 1 and Group 2 of the periodic table. These elements have their outermost electrons in the S sublevel before transitioning to the D sublevel in subsequent groups.
made of 2 or more substances
base in my experience.... because of the gravity of the earth...
The general name given to the elements of Group IA (1) is alkali metals.
Uranium ia a radioactive and toxic element.

Both Group IA and IIA elements have low ionization energies because they have one or two valence electrons that are easily removed. Group IA elements have a lower ionization energy compared to Group IIA elements due to the increased distance from the nucleus and increased shielding effect in Group IA.
