5.2 Flashcards
Ionic Bonds
This is the stealing of electrons between elements to fill the outer shell.
Charges after ionic bonding
The element with the electron being taken will have a -1 charge. The element gaining a proton will have a +1 charge.
Bonding happens to create…
Stability
Atoms are more stable when…
Their outer shell is full (8 valence electrons)
Nonmetals gain or lose electrons
lose
Metals gain or lose electrons
gain
Electronegativity
Measures how strongly atoms attracts NEW bonding electrons to themselves.
The electronegativity get weaker to stronger moving
left to right and down to up
Covalent bonds
Sharing/fighting of valence electrons
non polar covalent bonds
This is where all the charges are neutral
Polar covalent bonds
There is a difference in the charges
