Among the choices above the best describe the next step that a student would to after gathering of data, collecting of data and form graphs is to analyze and conclude all the data that information that has been collected. Thank you for posting your question here. I hope it helps.
Answer;
D. The group number is equal to the number of valence electrons.
Explanation;
-The valence electrons are the electrons in the outer shell of an atom. The valence electrons are the ones involved in forming bonds to adjacent atoms. Therefore, the number of valence electrons is important for determining the number of bonds an atom will form, the number of unpaired electrons, and an atom’s formal charge.
-For neutral atoms, the number of valence electrons is equal to the atom’s main group number.
Number of valence electrons = main group number (neutral atoms)
-The main group number for an element can be found from its column on the periodic table. For example, carbon is in group 4 and has 4 valence electrons. Oxygen is in group 6 and has 6 valence electrons.

n=no. of bullets = 1
m=mass of bullets=2g *10^-3
V=velocity of bullets200m/sec
F=1
loss in Kinetic energy=gain in heat energy
1/2MV^2=MS∆t
let M council M
=1/2V^2=S∆t
M=2g
K.E=MV^2/2
=(2*10^-3)(200)^2/2
2 councils 2
2*10^-3*4*10/2
K.E=40Js
H=mv∆t
(40/4.2)
40Js=40/4.2=mc∆t
40/4.2=2*0.03*∆t

The law of inertia pertains to both objects at rest and objects travelling in uniform motion (constant rate of motion so acceleration = 0).
ie of an object at rest: A person pushes a building with as much force as possible. The building is at rest and doesn’t move due to its inertia.
ie of an object travelling in uniform motion: An apple is thrown out of a car window. The apple bounces and moves on the ground after it is thrown out the window because of its inertia.
