Atoms and elements are related in that elements consist of one specific kind of atom. This means that the atom is the base unit of an element. Atoms consists of a nucleus, which contains protons, neutrons and electrons that orbit around the nucleus.Know More
Hydrogen is an element composed of atoms that have one proton and one electron. However, different isotopes of hydrogen have varying numbers of neutrons.
Different elements have different numbers of protons, which determines an element's atomic number. On the periodic table, the atomic number identifies the specific element and how many protons are in its nucleus. For example, carbon has six protons, so its atomic number is 6.
When two or more elements react chemically, they form a substance called a compound. Some examples of compounds are calcium carbonate (CaCO3) and sodium chloride (NaCl).Learn more about Atoms & Molecules
The relationship between atoms and molecules is the way molecules are made up of atoms. Atoms that are in groups of two or more are called molecules.Full Answer >
There is no universal net charge for atoms. An atom's net charge is determined by comparing the number of protons and electrons that are in each atom.Full Answer >
Dalton's atomic theory states four critical truths about atoms: firstly, everything is made up of atoms and atoms cannot be destroyed. Secondly, all atoms within a single element are identical. Thirdly, compounds are formed from two or more different kinds of atoms. Finally, chemical reactions rearrange atoms.Full Answer >
Electrons are shared in a covalent bond when each of the participating atoms has roughly the same ability to attract electrons. The more evenly the two atoms are able to pull the participating electrons towards themselves, the more evenly the electrons share their time around each atom.Full Answer >
