So, he could not say anything about the numbers of each atom in the molecules of specific substances. Did water have one oxygen with one hydrogen or one oxygen with two hydrogens? This point was resolved when chemists figured out how to weigh atoms. The ability to weigh atoms came about ...
An atom has three types of very tiny particles called protons, neutrons and electrons. The center of an atom is called the nucleus, and it is made up of protons and neutrons. The electrons in an atom fly around and above the nucleus in a cloud-like formation. The protons have a positiv...

The number of protons in an atom is unique to each element. For example,carbonatoms have six protons,hydrogenatoms have one andoxygenatoms have eight. The number of protons in an atom is referred to as the atomic number of that element. The number of protons also determines the chemical be...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...
An oxygen atom contains eight electrons, arranged into two orbital shells. Electron Situated within the two shells, these subatomic particles have a mass of almost zero and a charge of -1. Unpaired electron Two electrons in the outer shell don’t have a partner. This allows oxygen atoms to ...

Similarly, hydrogen and oxygen, which are both gaseous elements can combine to form water, which is a liquid compound, not a gas, at room temperature. The process by which such combinations and transformations of elements into compounds take place is called achemical reaction. ...
of plus three (N+3). All of these are monatomic ions, even though they have a charge that is more than 1, because they are composed of a single atom. An ion with a positive charge, such as Na+, is called a cation, while one with a negative charge, such as Cl-, is an anion...
