covalently bonded
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.
Chloride of what? The word chloride can refer to a chemical compound in which one or more chlorine atoms are covalently bonded in the molecule. This means that chlorides can be either inorganic or organic compounds. The simplest example of an inorganic covalently-bonded chloride is hydrogen chloride, HCl (a colorless acid). A simple example of an organic covalently-bonded (an organochloride) chloride is chloromethane (CH3Cl), often called methyl chloride (a colorless gas). Sodium Chloride is (as a monocrystalline solid) colorless but as a powder, opaque.
molecule
A charged group of covalently bonded atoms is called a polyatomic ion.
It depends on which two ions are bonded ionically. But normally most ionic bonds' melting points are really high - sometimes even reaching 3000 degrees Celsius or more. It is similar to those of the metals.
An ionic compound is more soluble than a covalently bonded compound.
A Molecule
NO! These two chemicals could hardly be more different: Sodium hydroxide is an ionically bonded inorganic salt that contains no carbon, while alkenes are organic compounds that are covalently bonded, contain no sodium or oxygen, and include a carbon-carbon double bond.
No, a single atom would have to belong to a particular element. A compound must contain two or more different types of atom that are chemically bonded (either covalently or ionically) together.

Carbon Dioxide (CO2). Compounds tend to be made from 2 or more different elements bonded together either covalently or ionically. They are all made of 2 or more elements bonded together whether those elements are the same or not. The other options are elements (Fe, O, and Ca respectively). They are not bonded to anything and therefore do not make a compound.
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.
Nitrogen in its elemental form is covalently bonded. A free element cannot be ionically bonded.
A covalently bonded molecule.
molecular compounds
An element is any substance that consists of only one type of atom, that is all atoms have the same number of protons. A compound is a substance that has two or more elements chemically bonded together either covalently or ionically in a fixed ratio. A molecule is a particle that consists of two or more atoms covalently bonded together. A molecule can have atoms of a single element (such as O2 or P4) in which case it is an element or it can consist of multiple elements (such as CO2 or H2SO4) in which case it is considered a compound.
