Why do valence electrons form bonds to create molecules and compounds? a. they are weaker than the electrons found closer to the nucleus. b. they are smaller than other electrons c. they are smaller than other electrons d. they are stronger than the electrons found closer to the nucleus note: yes, i am aware of b and d being the same, i have no clue for why that is.

Valence electrons form bonds to create molecules and compounds because A. they are weaker than the electrons found closer to the nucleus.

A better way of saying it is that the valence electrons are less strongly attracted to the nucleus.

All electrons have the same size, but the orbitals they occupy have different sizes.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
