what is group 3a on the periodic table?
536898
Group 3A (or IIIA) of the periodic table includes the metalloid boron (B), as well as the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). ... They are relatively soft metals, with lower melting points than many of the Group 2A metals.
502154
Group 1 - the alkali metals. The Group 1 elements in the periodic table are known as the alkali metals. They include lithium, sodium and potassium, which all react vigorously with water to produce an alkaline solution.
282870
Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). ... In most cases, the alkaline earth metals are ionized to form a 2+ charge.
1087054
Boron group element. ... Boron group element, any of the six chemical elements constituting Group 13 (IIIa) of the periodic table. The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh).

['The elements are arranged based on their increasing atomic number.', 'There are 7 periods and 18 groups in the table.', 'The inert gases i.e. He, Ne, Ar, etc. ... ', 'All the groups are divided into sub groups A and B except 0 and VIII group in the modern periodic table.']

Elements in group seven have a number of similar properties, most importantly they have low melting and boiling points. This is of course a typical property of non-metals. From the lowest boiling and melting point to the highest, the group in order is fluorine, chlorine, bromine, iodine and astatine.

Bromine is the third halogen, being a nonmetal in group 17 of the periodic table.

Lithium is the element that is atomic number 3 on the periodic table. These means each atom contains 3 protons. Lithium is a soft, silvery, light alkali metal denoted with the symbol Li.
910587
Groups of the periodic table. The s-, p-, and d-block elements of the periodic table are arranged into 18 numbered columns, or groups. The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
911854
Argon is a chemical element with the symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. Argon is the third-most abundant gas in the Earth's atmosphere, at 0.934% (9340 ppmv).
645
Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals. Groups are numbered 1–18 from left to right.
1255193
The boron group are the chemical elements in group 13 of the periodic table, comprising boron (B), aluminium (Al), gallium (Ga), indium (In), thallium (Tl), and perhaps also the chemically uncharacterized nihonium (Nh).
817938
Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). ... The name comes from the fact that when these metals or their oxides are dissolved in water, a basic (alkaline) solution results.
1016725
Lithium, sodium, and potassium are placed in the same group on the periodic table because all three elements rhyme and also those three elements have qualities that are really simular.
934330
Group 15 of the periodic table is also called the nitrogen group. The first element in the group is the nonmetal nitrogen (N), followed by phosphorus (P), another nonmetal. Arsenic (As) (Figure below) and antimony (Sb) are the metalloids in this group, and bismuth (Bi) is a metal.
