The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.Jun 5, 2019
What is the difference between family and group in periodic table?
Groups: The vertical column of the periodic table that signifies the number of valence electrons in an element. Periods: The horizontal rows in the periodic table that signify the number of electron shells in an element. Families: Elements that have the same number of valence electrons and therefore similar properties.
What is the family number on a periodic table?
The group/family number is the number assigned to the vertical columns of the periodic table. Elements within the same group have the same number of valence electrons. This similar electron configuration leads to the elements in the same group having similar chemical properties.
What is a family or group of elements?
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 2 and 3) are not numbered.
Are groups and families the same thing?
For the most part, element families and element groups are the same things. Both describe elements that share common properties, usually based on the number of valence electrons. Usually, either family or group refers to one or more columns of the periodic table.
Why are groups sometimes called families?
The groups in the Periodic table are also called Families because; The elements lying in the same group have same number of valence electrons, which results in their similar properties (like similar habits of all the family members.)
What are the 5 families of elements?
Families on the periodic table include, in addition to noble gases and halogens, the alkali metals, alkaline earth metals, transition metals, lanthanides, and actinides.
What are the 4 families on the periodic table?

How many groups families are on the periodic table?
18 groupsThere are 18 groups, according to the modern Periodicals Table. There are eight major groups in the periodic table: 1, 2, 13, 14, 15, 16, 17 and 18 (previously numbered Ia, IIa, IIIa, IVa, Va, VIa, VIIa, and 0, respectively).
What is the family name of elements in group 17 of the periodic table?
halogenhalogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).

The Callan Periodic Table of Investment Returns graphically depicts annual returns for various asset classes, ranked from best to worst. Created by Jay Kloepfer in 1999, the table features well-known, industry-standard market indices as proxies for each asset class. “The enduring appeal of the table is its ability to be understood at a glance,” says Kloepfer.

As we move past the first eighteen elements, you can start to learn about transition elements in the fourth period (row) of the periodic table.The transition metals have electron configurations that are a little different from the first eighteen. Make sure you understand the basics of electron orbitals before you move on to this row.

· periodic table, in full periodic table of the elements, in chemistry, the organized array of all the chemical elements in order of increasing atomic number—i.e., the total number of protons in the atomic nucleus. When the chemical elements are thus arranged, there is a recurring pattern called the “periodic law” in their properties, in which elements in the same column …

The periodic table we use today is based on the one devised and published by Dmitri Mendeleev in 1869. Mendeleev found he could arrange the 65 elements then known in a grid or table so that each element had: 1. A higher atomic weight than the one on its left. For example, magnesium (atomic weight 24.3) is placed to the right of sodium (atomic ...
