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.

Which groups are considered families?
5 Element Families
- Alkali metals.
- Alkaline earth metals.
- Transition metals.
- Halogens.
- Noble gases.
What is a family or group?
A family is a group of people related by the ties of blood, marriage, or adoption.
How are groups organized on the periodic table?
The chemical elements are arranged in order of increasing atomic number. The horizontal rows are called periods and the vertical columns are called groups.This is because they have the same number of outer electrons and the same valency. An example of a group in the periodic table is the alkali metal group.
How many groups are families?
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.
What elements are designated as family members of arsenic?
Arsenic is found in the fourth period/row of the table of elements. It is a member of the phosphorus family with other elements including phosphorus (duh), antimony (Sb), and bismuth (Bi).
What makes a family a family?
A family is a group of people going through the world together.Some families include single-parent, adoptive, or LGBT families; children living with grandparents; children living with large extended families, including grandparents, aunts, uncles and cousins; and children splitting time among different family members.
What is a family and types of family?
We have stepfamilies; single-parent families; families headed by two unmarried partners, either of the opposite sex or the same sex; households that include one or more family members from a generation; adoptive families; foster families; and families where children are raised by their grandparents or other relatives.
Are groups and families the same thing?
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 do groups on the periodic table represent?
The periodic table also has a special name for its vertical columns. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons.
Who organized the periodic table?
chemist Dmitri Mendeleev
In 1869, Russian chemist Dmitri Mendeleev created the framework that became the modern periodic table, leaving gaps for elements that were yet to be discovered. While arranging the elements according to their atomic weight, if he found that they did not fit into the group he would rearrange them.
What are the groups of elements?
Elements Organized by Group
- Group 1: Hydrogen and the Alkali Metals.
- Group 2: The Alkaline Earth Metals.
- Group 3: Transition Metals.
- Group 4: Transition Metals.
- Group 5: Transition Metals.
- Group 6: Transition Metals.
- Group 7: Transition Metals.
- Group 8: Transition Metals.
What are groups and how many groups in periodic table?
Groups are numbered from 1 to 18. From left to right in the periodic table, there are two groups (1 and 2) of elements in the s-block, or hydrogen block, of the periodic table; ten groups (3 through 12) in the d-block, or transition block; and six groups (13 through 18) in the p-block, or main block.
Which of the following belongs to Group 18?
Answer: (C)Ar i.e. Argon is a Noble gas. And all the noble gases falls under group 18. Other Noble gases are:- Helium, Neon, Krypton, Xenon, Radon and Organesson.
What are the two main set of families or groups in the periodic table?
Key Concepts and Summary
Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 are the pnictogens; those in 16 are the chalcogens; those in 17 are the halogens; and those in 18 are the noble gases.
What is the family group of arsenic?
nitrogen group element
nitrogen group element, any of the chemical elements that constitute Group 15 (Va) of the periodic table. The group consists of nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi), and moscovium (Mc).
Which group is known as arsenic group?
nitrogen group
arsenic (As), a chemical element in the nitrogen group (Group 15 [Va] of the periodic table), existing in both gray and yellow crystalline forms.
What metal is grouped with metalloids?
The post-transition metals cluster to the lower left of this line. Metalloids: The metalloids are boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te) and polonium (Po). They form the staircase that represents the gradual transition from metals to nonmetals.
What truly makes a family?
A family could include grandparents, aunts and uncles, godparents, or close friends. What is important is the love or common interests that bind them together. Regardless of biological relationship, you may be a part of several “families.” Your school classmates may be a family to you. Your soccer team may be a family.
What is an joint family?
joint family, family in which members of a unilineal descent group (a group in which descent through either the female or the male line is emphasized) live together with their spouses and offspring in one homestead and under the authority of one of the members.
Who makes a family answer?
Family is defined as a group of people consisting children, parents, aunts, uncles, cousins and grandparents.
