Atoms: Composed of a neutron and proton nucleus, which is surrounded by an electron cloud. Can only be seen with powerful microscopes. Composed of negatively charged electrons that surround a nucleus of positively charged protons and neutrons, who have no charge. Protons and neutrons of the atom's nucleus are bound by nuclear force. In turn, electrons are bound to the atom by electromagnetic force.
Molecules: Composed of two or more atoms. Vary in size. Electrically neutral. Opposites attract, and the interaction between electrons and protons of separate atoms creates the chemical bonds that form molecules.

What else can I help you with?
What type of bond exists between atoms when the difference in electronegativity is 0.9?
When the difference in electronegativity between atoms is 0.9, a polar covalent bond exists.
If the difference in electronegativity between two atoms is between 0 and 0.5 the bond formed is?
The bond formed is nonpolar covalent if the difference in electronegativity between two atoms is between 0 and 0.5. This means that the electrons are shared equally between the atoms in the bond.
What is the electronegativity equation used to calculate the difference in electronegativity between two atoms in a chemical bond?
The electronegativity equation used to calculate the difference in electronegativity between two atoms in a chemical bond is the absolute difference between the electronegativity values of the two atoms. This is represented as A - B, where A and B are the electronegativity values of the two atoms.
What values best classifies a bond between 2 atoms as being covalent?
An electronegativity difference of less that 1.7 between the atoms
What determines the type of bond that forms between atoms or compounds?
The type of bond that forms between atoms or compounds is determined by the electronegativity difference between the atoms involved in the bond. If the electronegativity difference is small, a covalent bond forms, where electrons are shared. If the electronegativity difference is large, an ionic bond forms, where electrons are transferred.
Are atoms and molecuels the same thing?
No they are not the same thing because a group of atoms are called a molecuele and plus you can split a molecuele but not a atom. Your welcome
What type of bond exists between atoms when the difference in electronegativity is 0.9?
When the difference in electronegativity between atoms is 0.9, a polar covalent bond exists.
If the difference in electronegativity between two atoms is between 0 and 0.5 the bond formed is?
The bond formed is nonpolar covalent if the difference in electronegativity between two atoms is between 0 and 0.5. This means that the electrons are shared equally between the atoms in the bond.
How can the type of bond be predicted?
Ionic bond: the difference between electronegativities of the atoms is over 2.Covalent polar bond: the difference between electronegativities of the atoms is under 2.Covalent non-polar bond: the difference between electronegativities of the atoms is cca. zero
What is the difference between liquid and solid steel?
the only difference is the energy of the atoms
What are molecuels?
A Compound :)

The difference between polar molecuels and nonpolar molecuels?
A polar molecule in which there is some separation of charge in the chemical bonds, so that one part of the molecule has a slight positive charge and the other a slight negative charge. A common example of polar molecule is water. The water acts as a solvent for polar molecules. A non-polar molecule has no separation of charge, so no positive or negative poles are formed.

How do you spell molecuels?
molecules
How do you predict the type of bond between two atoms?
Some general rules are:- the difference between the electronegativities of two atoms is over 2: ionic bond- the difference between the electronegativities of two atoms is in the range 0 -2: covalent bond- the difference between the electronegativities of two atoms is approx. zero: polar covalent bond
