The compounds are either held together by ionic bonds which are formed between a cation and anion or by covalent bonds which are formed when atoms share electrons with each other.
Most of the compounds are formed by covalent bonds.
Example:- HF, NaCl, LiF etc. are formed by ionic bonding
CH4,H2O, HCl etc. are made from covalent bonding.

∙ 9y agoBy sharing electrons. The most stable configuration for an atom is to have its electron shells filled with the requisite number of electrons for its shells. (The "noble gasses" are in this state which is why they do not react to form compounds).
Thus if an atom with just one electron in a shell that could contain 6 meets an atom with a sell that is incomplete by one electron, it is more stable for that atom to "loan" its extra electron to this new atom than for both atoms to exist apart. Thus one atom gives up its electron to revert to its last filled shell and the other atom gains an electron to complete its shell.
The donating atom therefore becomes positively charged overall (an "ion" - a "cation") while it partner becomes negatively charged overall (an "ion" - an "anion"). The two atoms are therefore bonded together electrically.

∙ 12y agoThere are three types of bonding, but these are the most common types
1. ionic- when the atom with the most electron affinity attracts electrons from one or more other atoms to create that bond.
2. covelent- the atoms join together sharing their valance electrons. (this is how diatomic elements bond)

What is it called when two different atoms combine?
Answer:molecular compound
When two or more atoms form together what do they make?
A compound. (Could also be a mixture depending on if they are fused together or mixed)
What kind of atoms make up the compound iodine?
Iodine is not a compound. It is an element. Therefore, it has its own atoms: Iodine atoms.
What are the characteristics of chemical bonds?
Recall that atoms also can loan electrons to other atoms so that both can reach a stable energy level. When atoms gain, lose, or share electrons, an attraction forms that pulls the atoms together to form a compound. A compound has different physical and chemical properties from those of the atoms that make up the compound.
How do the properties of a compound compare with the properties of the elements that make up the compound?
Compounds have different properties from the elements that make them. ... The properties of a compound depend not only on which atoms the compound contains, but also on how the atoms are arranged.
Are compounds formed when atoms of two different elements join together?
Yes, two or more different atoms of two or more different elements will, when chemically bonded, make a chemical compound.
When different kinds of atoms join together what do they make?
Compounds
What atoms join together to make water?
Two atoms of hydrogen and one atom of oxygen.
How are atoms related to molecules in a sample of a compound?
atoms are made of molecules and that is why they are related !
If atoms from different elements join together what does it make?
chemical bond
When two or more atoms link together they make a...............?
There are two possible answers : compound, or molecule.
How do you make a compound sentence?
You join 2 independent clauses together with a conjunction.
Do cells combine to make atoms?
Wrong way around. Atoms join together to create molecules. These molecules then join other molecules to create cells.
Who is the man that proposed that atoms join together to make up compounds?
john dalton
How do atoms join to together to make different substances?
There are two different types of bonds when atoms join together. Covalent bonds are formed when atoms "share" electrons. Ionic bonds are formed when an atom gives up its electrons to another to form a bond.
Why do atoms make up molecules but molecules don't make up atoms?
Atoms are the smallest possible units of PURE substances called elements. There are are only about 118 elements known to exist.When atoms of different elements join together chemically (they share electrons between each other), they form a new substance called a compound. The smallest possible unit (or joined up atoms) of a compound is called a molecule. There are potentially hundreds of thousands of compounds.
What happens when chemicals join?
When atoms of two different elements join together (or combine) to make molecules of a compound, scientists say that a Chemical Change or Chemical Reaction has taken place. I you look at the substances you start off with and the substance you get after the change, they are often different.
