Periodic table has 18 groups; see the link below.
Elements on the periodic table are usually identified by their atomic number, atomic symbol, and atomic weight. The atomic number represents the number of protons in the nucleus, the atomic symbol is a one- or two-letter abbreviation for the element, and the atomic weight represents the average mass of the element's atoms.
The last element in the 3rd group of the modern periodic table is gallium, with the symbol Ga. Gallium has a valency of +3, meaning it tends to lose three electrons to achieve a stable electron configuration.
See the periodic table at the link below.
The three main element groups are alkali metals , alkaline earth metals and halogen family.
The 88th element on the periodic table is radium. The symbol for radium is Ra. This element is radioactive and emits three types of radiation.
Hydrogen is placed separately. It has one valence electron. It is placed at the top in periodic table.
Elements such as oxygen, silicon, and carbon are commonly associated with three things: atomic number, atomic mass, and chemical symbol. These properties help uniquely identify each element on the periodic table.

The periodic table can tell you the atomic number, atomic symbol, and atomic mass of each element listed. It also provides information on an element's properties, such as its reactivity and basic chemical behavior. Additionally, the periodic table organizes elements into groups and periods based on their similar chemical properties and electron configurations.
There are 6 orange colored tabs on the periodic table of elements, the Alkaline Earth Metals, which are Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium. But of course, not all periodic tables have the same color scheme so this may be incorrect.
The first element in period three of the periodic table of chemical elements is sodium (Na).
It's the element Lithium, it's on the periodic table of the elements.
NOT as 'diamond'. However, diamond is an allotrope of carbon . Carbon is found in the periodic table. as 'C'. NB Diamond, Graphite and Buckminster Fullerene (Footballene) are three allotrop[es of of Carbom . NOT isotopes. An Allotrope is an element that exists in different physical form.

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
