The Parts of the Periodic Table

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. The Group 3A metals have three valence electrons in their highest-energy orbitals (ns 2 p 1).

B. The metals in Group IIIA, IVA, and VA of the periodic table are not transition metals. However, all but 1 have variable charges. What element in Group IIIA, Period 3 has a fixed charge, and what is that charge? Group III A elements are now called group 13 elements and in the period 3 it is aluminium.

periodic table | Definition & Groups | Britannica

Nov 20, 2019· Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the 'periodic law' in their properties, in which elements in the same column (group) have similar properties.

2.3: Families and Periods of the Periodic Table ...

Periods of the Periodic Table. If you can locate an element on the Periodic Table, you can use the element's position to figure out the energy level of the element's valence electrons. A period is a horizontal row of elements on the periodic table. For example, the elements sodium ((ce{Na})) and magnesium ((ce{Mg})) are both in period 3.

Group 14 (IVA) - ChemEd DL

Group 14 of the periodic table is often referred to as the carbon group. It is located in column 14 of the periodic table and houses the elements carbon, silicon, germanium, tin, lead, and ununquadium (C, Si, Ge, Sn, Pb, and Uuq, respectively). Each element in this group contains four valence electrons.

Element Families of the Periodic Table - ThoughtCo

Oct 28, 2019· An element family is a set of elements sharing common properties. Elements are classified into families because the three main categories of elements (metals, nonmetals, and semimetals) are very broad.The characteristics of the elements in these families are determined primarily by the number of electrons in the outer energy shell.

The Difference Between an Element Group and Period

Aug 10, 2019· Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.

What element is found in group 3A and period 6 - Answers

Although boron is a metalloid and the other elements in group 3A of the Periodic Table are metals, it is placed with group 3A because it has three valence electrons at its highest-energy orbitals.

Periodic table - Wikipedia

In the periodic table of the elements, each numbered column is a group.. In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements.There are 18 numbered groups in the periodic table; the f-block columns (between groups 3 and 4) are not numbered. The elements in a group have similar physical or chemical characteristics of the outermost ...
