One of the ways the Periodic Table is organized is by rows. After Hydrogen, the next four elements is: Lithium, Sodium, Potassium and Rubidium. These are also in the same Group as Hydrogen therefor they are the closest to having similar properties to Hydrogen.
I'm studying the Periodic Table in class. (Eighth grade Science.)
The four elements that make up most of living matter are hydrogen, oxygen, carbon and nitrogen.
Carbon, Hydrogen, Nitrogen, and Oxygen are the four most common elements.
The four most common elements in the human body are carbon, hydrogen, oxygen and nitrogen.
Flourine belongs to a class of elements called Halogens, which are similar in their chemical and physical properties. The other elements of this group are Chlorine, Bromine, Iodine, Astatine and Ununseptium. Astatine, however, is not considered to be a true halogen since it is radioactive in nature and Ununseptium is a synthetic element.
Carbon, Hydrogen, Oxygen
All substances are MADE FROM elements but they are not elements. For example CH4 is made of one carbon atom and four Hydrogen atoms. Carbon and Hydrogen are pure elements but CH4 is not an element.
Four physical properties shared by the metallic elements are that they are ductile, malleable, have good thermal conductivity, and have a metallic luster. They are also good conductors of electricity.
4 ELEMENTS IN A CELL? hydrogen, oxygen, nitrogen, carbon
Methane contain 1 carbon & 4 hydrogen elements.
Carbon, Hydrogen, Nitrogen, Oxygen
The other four halogens in column VII A of a narrow form or column 17 of a wide form periodic table: chlorine, bromine, iodine, and astatine.
There are four elements in NH4F.They are Nitrogen,Fluorine and Hydrogen.
