Atoms are made up of a positive proton, neutral neutron, and negative electrons. While the two front ones are in the middle of the atom, the negative electrons surround them in certain areas, called shells. There are a given number for the most electrons that can occupy a shell. (except Hydrogen, since it has only one proton and one electron, not even a neutron), but, otherwise, on the first shell there could be no more than 2 electrons, on the second no more than 8, and so forth. Since all element has it own particular number of electrons, they fill up the shell accordingly. (Mind you, they don't have to fill up the particular shells, but they cannot be more of them on the shell what is allowed). The most important is the most outer shell, the so called valence shell. On that one it must be the right number of electrons that left after the other shells would have filled to total capacity. Only atoms with complette number (the most possible number) of electrons are stable. Like the noble gases. They are the most stable atoms, and those stability is seeked by all the other atoms. The more the valence shell is filled up in an atom, the more stable it is. The less electrons are in the valence shell, the less stable those atoms are. For these reasons, those with just a few electrons short of a filled valence shell, try to poach electrons from atoms that only have a few on their valence shell. You can try to read Electronegativity to understand it better. So, in their effects to fill up the valence shell, atoms donate, accept, or share electrons. More of that in bonds. I hope it helped a little.
Like charges do not attract each other, they repel each other.
In a covalent bond, atoms share electrons to achieve stability. The charge of the atoms involved determines how strongly they attract or repel each other in forming the bond.
"Opposites attract". So two electrons repel each other.
When two opposite electrical forces are near each other, they will attract each other. This attraction is due to the presence of opposite charges, which exert a force on each other. The strength of the attraction will depend on the magnitude of the charges and the distance between them.
If two chlorine atoms attract electrons from two calcium atoms, they will form ionic bonds. The chlorine atoms will gain one electron each to achieve a full outer shell, forming chloride ions, while the calcium atoms will lose two electrons each to become calcium ions. The resulting compound will be calcium chloride, with the formula CaCl2.
Atoms with the same charge are pushed away from each other. Atoms with different charge attract (unite)
Not positive
Yes, that is how they attract to each other to create molecules.
I'm not sure what you mean by "combine", but if atoms are similarly charged, they will not attract... in fact, they will repel each other.
If the atoms have opposite charges (positive to negative) they will attract. If the atoms have the same charges (positive to positive or negative to negative) then they will repel. You can look at the Law of Electric Charges to get more information on this.
When positive and negative ions attract each other, an ionic bond is formed. Ionic bonding refers to the complete transfer of valence electron between atoms.
They attract each other when they have differed charges, or to involve in chemical bonding.
No they can not attract each other.
The H atoms with partial + charges attract O atoms with partial - charges on other water molecules.
Unlike poles attract each other
Like charges do not attract each other, they repel each other.
Due to their electron configuration, the atoms in a noble gas hardly attract each other.
