Chapter 5: Covalent Compounds and Their Chemistry

Question 1

what is a homonuclear diatomic?

Answer 1

A molecule consisting of two atoms of the same element

Question 2

what is a covalent bond?

Answer 2

A chemical bond that is made by sharing electrons

Question 3

True/false: hydrogens, ideal electron configuration consists of two valence electrons, not eight

Answer 3

true

Question 4

what are covalent compounds?

Answer 4

A compound who’s elements are held together with covalent bonds

Question 5

True/false: covalent compounds do not contain metals

Answer 5

true

Question 6

what is atomic radius?

Answer 6

The distance from the center of the nucleus to the atoms valence electrons

Question 7

True/false: as you travel up the periodic table, and to the right, the atomic radius increases

Answer 7

false

Question 8

what is electronegativity?

Answer 8

A measure of how strongly atoms attract electrons in a covalent bond

Question 9

True/false: as you travel up the periodic table, and the right electronegativity increases

Answer 9

True

Question 10

what is a polar covalent bond?

Answer 10

A covalent bond in which the electrons are not shared equally

Question 11

what is a polar covalent molecule?

Answer 11

A molecule that has an uneven distribution of electrons resulting in slight charges within the molecule itself

Question 12

True/false: a polar covalent molecule must have polar covalent bonds

Answer 12

True

Question 13

what is a purely covalent bond?

Answer 13

A covalent bond in which electrons are shared equally

Question 14

what is a purely covalent molecule?

Answer 14

Molecule that has an even distribution of electrons resulting in no charges within a molecule itself

Question 15

True/false: a polar covalent molecule must have polar covalent bonds that don’t pour equally in all directions

Answer 15

True

Question 16

True/false: polar compounds tend to dissolve well, and other polar compounds and ionic compounds tend to dissolve, well in polar compounds. nonpolar compounds, usually dissolve well, in other nonpolar compounds, as well as polar compounds

Answer 16

false: nonpolar compounds don’t dissolve well with polar compounds
