Electronegativity and Bonds Quizizz

An ionic bond occurs because a nonmetal with a very ​ (a)   electronegativity can steal valence electrons from a metal with a ​ low electronegativity. This causes the metal to form a ​ (b)   charge and the nonmetal to form a ​ (c)   charge. These opposite charges will allow the charged metal and nonmetal atoms to ​ (d)   .

• high
• positive
• negative
• attract

A covalent bond would share electrons equally because the electronegativity difference between two atoms is very ​ (a)   . This means that either of the two atoms sharing electrons does NOT have too much of a greater ​ (b)   for the shared electrons, which causes the atoms to share the electrons in a bond ​ (c)   .

• low
• pull
• equally

• Polar
• unequally
• equally
• more
• less
• Non-Polar

Carbon has an electronegativity of 2.55. Two carbon atoms bonding together would form a ​ (a)   bond. This would be because the 2.55 electronegativity would ​ (b)   out since both carbon atoms evenly ​ (c)   the shared electrons with the ​ (d)   strength.
