Nitrogen, Oxygen, Flourine, and Chlorine. Bromine and Iodine are both joined together in their own molecule, but Bromine is a liquid and Iodine is a solid. The way i remember these 'diatomic' (they are elements in pairs of two atoms to a molecule) elements is by, NOFClBrI. Sticks in your head and they form an upside down 'L' shape in the Periodic Table.
nitrogen, oxygen, fluorine, chlorine are all diatomic (2 atoms in the molecule) at room temerature and pressure.
Oxygen would be such an element (as would hydrogen, nitrogen, fluorine, chlorine).
The choices are hydrogen gas, H2; nitrogen gas, N2; and oxygen, O2.
Two or more atoms of different elements joined together form a compound. If it is a metal and non-metal (for example sodium and chlorine), they are ionically bonded. If it is two non-metals (for example methane is carbon and hydrogen), they are covalently bonded.
An element consist of one type of atom only but atoms of elements are joined together to make compounds.
They create molecules. If the atoms joined together are from different elements they create polar molecules.
Molecule if they are chemically bonded, cluster if not. J Ayres
Molecule
Elements are those substances which have same constituent particle altogether. Molecules are a group of atoms joined together . Atoms of elements join together to form a molecule.
Molecules are made of more two or more atoms joined together. The atoms can be same or different elements. A single molecule is the smallest piece of matter.
atoms
because they are chemically joined together and it is difficult to separate them
Two or more atoms joined together form a molecule. You can't say compound because you do not specify that the atoms are of different elements. You can have a molecule of oxygen because two or three atoms of oxygen can couple together by themselves, but it is not a compound, it is a molecule of oxygen.
Two or more atoms of different elements joined together form a compound. If it is a metal and non-metal (for example sodium and chlorine), they are ionically bonded. If it is two non-metals (for example methane is carbon and hydrogen), they are covalently bonded.
An element consist of one type of atom only but atoms of elements are joined together to make compounds.
In a molecule, atoms are joined together by bonds. When we say bonding, we are referring to these bonds.
mabey it depends
This is the definition of a compound: a substance that contains atoms of two or more chemical elements held together by chemical bonds.
They create molecules. If the atoms joined together are from different elements they create polar molecules.
