electron |
|
atom |
|
neutron |
|

A proton is a subatomic particle found in the nucleus of an atom. It carries a positive electric charge.
The angle of reflection is equal to which the following?
90° |
|
angle of incidence |
|
refractive index |
|
focal point |
The law of reflection specifies how waves, including light waves, bounce off of surfaces. Specifically, the angle of incidence of the approaching wave is equal to the angle of reflection of the reflected wave as measured from a line perpendicular (90°) to the surface.
Which of the following represents the largest value?
1 ML |
|
1 kL |
|
1 mL |
|
1 cL |
Mega (M) is 106, kilo (k) is 103, centi (c) is 10-2, milli (m) is 10-3 so 1 ML represents the largest value.
Elements that belong to the same period in the Periodic Table of the Elements have the same number of:
electron shells |
|
electrons |
|
atomic mass units |
|
protons |
The rows of the Periodic Table are called periods and contain elements that have the same number of electron shells ordered from lower to higher atomic number.
