5.2 Study Guide Flashcards
What happens with electrons in a covalent bond
Atoms fight over electrons
Atoms pulled together
Which type of atoms attract electrons strongly
Nonmetals
A covalent forms between what atoms
Two nonmetal atoms
Is hydrogen considered a metal or nonmetal
Nonmetal, will form covalent bonds with other nonmetals
As atoms get closer, does the potential energy increase or decrease, why
Decrease because each atom is attracting the other atom’s electrons more and more strongly
As the atoms get closer the protons will start doing what to each other
Repelling each other
Atoms at their lowest potential energy
Most stable
What is bond length
Distance between centers of two covalently bonded atoms
What forms when two electron pairs are being shared
Double bond
What forms when three electron pairs are being shared
Triple bond
Which type of bonds tend to be the strongest
Triple bonds
Metal has ______ attraction
Nonmetals has ______ attraction
Weaker
Stronger attraction
In ionic bonds who will always be the winner and the loser
Winner - nonmetal
Loser - metal
Non polar covalent bonds
Equal sharing of electrons
Polar covalent bonds
Unequal sharing of electrons
Ionic bonds
No sharing of electrons in bond
Bonding provides _______
Stability
Octet rule
8 valence electrons = most stable
Atoms are more stable when
They have a full outer valence shell
Whether atoms lose or gain electrons depends on
Attraction for valence electrons
Metals tend to ___ electrons
Lose
Nonmetals tend to ___ electrons
Gain
Electronegativity
Measure of how strongly atoms attract new bonding electrons to themselves
How do atoms form a covalent bond
Valence electrons attracted to both nuclei, fighting over them
Nonpolar ___ pull and electronegativity
Equal
Polar ___ pull and electronegativity
Unequal
Nonpolar charge
Neutral
