All of the atoms of a saturated hydrocarbon are bonded by 1 or 2 pair(s) of electrons.

Explanation:

A hydrocarbon is defined as a specie which contains atoms of carbon and hydrogen.

For example, is a hydrocarbon.

When there are only single bonds present in a hydrocarbon then it is known as a saturated hydrocarbon.

When a hydrocarbon contains a double or triple bond then it is known as an unsaturated hydrocarbon.

For example, is an unsaturated hydrocarbon.

Therefore, we can conclude that the statement all of the atoms of a saturated hydrocarbon are bonded by 1 or 2 pair(s) of electrons, is not true.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
