Atomic weight or mass
Atomic number
Atoms like to have a filled outer shell of electrons. Sometimes, by transferring electrons from one atom to another, electron shells are filled. The atom that gives away an electron will take a positive charge, and the receiving atom will have a negative charge. The charged atoms or ions will be attracted to each other, and form bonds.
Some atoms like to share electrons to complete their outer shell. Like this oxygen atom. It needs 2 electrons to follow the 2/8/8 rule. In this case to make water, you would need 2 hydrogen atoms. By sharing electrons the hydrogen atom is also able to complete it’s electron shell. Hydrogen bonds are primarily covalent bonds and a regular covalent bond is very strong.
Oxygen
On the Inside
• BY YOURSELF complete BOTH sides of the “On the Inside” worksheet.
You do NOT have to draw the Oxygen Atom
