Plllzzz plz plz plz plz plz match the element with its number of valence electrons. match term definition boron a) 1 carbon b) 7 fluorine c) 3 sodium d) 4 question 2 (fill-in-the-blank worth 2 points) (03.03 lc) the element oxygen has valence electrons. (input only a whole number, such as 7.) numerical answers expected! answer for blank 1: question 3 (true/false worth 2 points) (03.03 lc) sodium has more valence electrons than magnesium. true false question 4(multiple choice worth 2 points) (03.03 mc) element a has seven valence electrons. how does its reactivity compare to that of element b, which has four valence electrons? element a is more reactive. element a is less reactive.

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.
