What are the family names for Group 1?
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 in Group 1 of the periodic table?
Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.
What is an element family name?
element group
An element family is a column of elements on the periodic table. Each member of a family has the same number of valence electrons. Family members share similar chemical and physical properties. An element family is also called an element group.
What is Family 1 on the periodic table?
Alkali Metals or Group 1 Family of Elements The alkali metals are recognized as a group and family of elements. These elements are metals. Sodium and potassium are examples of elements in this family. Hydrogen is not considered an alkali metal because the gas does not exhibit the typical properties of the group.
What are the 10 families of the periodic table?
Terms in this set (10)
- alkali family. group 1, hydrogen is not a member.
- alkaline earth. group 2, also very reactive, only 2 valence electrons.
- transition metals.
- boron family.
- carbon family.
- nitrogen family.
- oxygen family.
- halogen family.
What is family in periodic table?
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.
What do all Group 1 elements have in common?
Atoms of group 1 elements all have one electron in their outer shell. This means that the alkali metals all have similar chemical properties . When a group 1 element takes part in a reaction, its atoms each lose one electron. This forms positively charged ions .
What are the 10 families of elements?
What are the three families of elements?
Recall that all elements can be classified into three categories: metals, nonmetals, and semiconductors. Scientists classify the elements further into five families. The atoms of all elements in most families have the same number of valence electrons.
How many families are there in periodic table?
So why do the elements in the same family have similar properties? You can examine four families on the periodic table and look at the electron configurations for a few elements in each family. The figure below lists some important families that are given special names: The IA family is made up of the alkali metals.
