Ethe table below for the next three questions.

ion symbol atomicnumber massnumber protons neutrons electrons
oxygen o-2 [a.] 16 8 [b.] [c.]

hints:

if an ion has a + charge, that indicates it has more protons (+) than electrons this means the atom has lost electrons.
if an ion has a - charge, that indicates it has more electrons than protons (+). this means the atom has gained electrons.

[a] corresponds to:

a. 2

b. 8

c. 16

d. none of the above

[b] corresponds to:

a. 2

b. 8

c. 16

d, none of the above

[c] corresponds to:

a. 2

b. 6

c. 8

d. 10

If a substance is not at its melting or boiling point, as the heat content of a sample of matter increases, its temperature increases the number of intermolecular bonds decreases the space between particles increases the particles move faster

Covalent network solids typically have melting points and boiling points. the chemical formula of a network solid indicates in the molecule.

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
