5.3 Types of Bonds

Question 1

What is a covalent bond?

Answer 1

bond formed between atoms when each contributes one or more of its unpaired valence electrons; electrons shared by both atoms

Question 2

What is polarity?

Answer 2

when electron density is uneven between two nuclei

Question 3

What is a dipole moment?

Answer 3

two equal but opposite electrical charges

Question 4

What is a polar covalent bond?

Answer 4

a covalent bond between atoms with differing electronegativity such that electrons spend more time in the vicinity of one atom than the other

Question 5

What is a nonpolar covalent bond?

Answer 5

homogeneous electron distribution and does not carry a dipole moment

Question 6

What is a coordinate covalent bond?

Answer 6

coordinate bond formed as a result of a lewis acid-base reaction most often formed between a metal and non metal

Question 7

What is a lewis base?

Answer 7

molecule that donates a pair of electrons

Question 8

What is a lewis acid?

Answer 8

molecule that accepts a pair of electrons

Question 9

What is an ionic bond?

Answer 9

strong electrostatic attraction between two oppositely charged ions; there is no electron sharing
