What element is in Group 3?
Group 3A. 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). Boron forms mostly covalent bonds, while the other elements in Group 3A form mostly ionic bonds.
Are groups 3/12 representative elements?
Group 1 elements are called alkali metals. Group 18 elements are called noble gases. Groups 1, 2, and 13-18 are the representative elements (or main-group elements). Groups 3-12 are called the transition metals.
What element is in Group 3 and period 5?
| Period | Group | |
|---|---|---|
| 2 | Li 3 | C 6 |
| 3 | Na 11 | Si 14 |
| 4 | K 19 | Ge 32 |

What are the three general groups on the periodic table?
Metals. Most elements are metals.
What do the groups tell you on the periodic table?
The group number tells you the total number of electrons present in the outermost orbit of an atom. In other words, group number tells you the number of valence electrons of an atom. Let us consider group 1 of the Periodic table. Group 1 indicates that the elements lying in that group have only 1 electron in its outermost orbit.
What is the largest group in the periodic table?
Transition Metals: Make up, by far, the largest family in the periodic table. They are located between and including the following elements horizontally: scandium through copper, yttrium through silver, lanthanum through gold, actinium through all higher atomic numbers in that period.
What do groups go by on the periodic table?
the horizontal rows are called periods
