is the same as the number of electrons that will be taken to form anions or the number of electrons which will be given away to form cations.
what is the outer shell of electrons called
valence shell
define covalent bond
bond formed between two or more atoms that share electrons
because atoms "want" to gain or shed electrons to fill outer shells, valence also describes how many
positions one moves on the periodic table to reach a noble gas column
define a double covalent bond
when two electrons are shared equally
Triple covalent bond is when
three electrons are shared from each atom
define a polar covalent bond
This kind of bond means that the atoms have a partial charge on them, so it has poles and it's called polar. Because this kind of bond has characteristics of a polar bond and a covalent bond... polar covalent bond
define ionic bond
when atoms hang out together because they have opposite charges.
What atoms are in the human body that form polar covalent bonds
Oxygen
Nitrogen
Sulfur
Ionic bonds are formed between
metal and non-metal ions
In a polar covalent bond the pull on electrons is measured in a quality called
electronegativity
define hydrogen bonds
are a special characteristic of compounds that contain hydrogen and oxygen, hydrogen and nitrogen, and hydrogen and sulfur
define a dipole
more positive charges at one end, more negative charges at the other
