The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses. Mass is the word for how much substance (or matter) something has.
Isotopes are atom families that have the same number of protons, but different numbers of neutrons
Each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
Answer:
<h2>
The answer is C </h2>
Explanation:
when a car begins to slow down the speed that it was going will decrease. Which means that it is an example of deceleration.
Answer:
Explanation:
Potential energy is converted into kinetic energy. I am 100% positive.
V= d/t
v=speed
d=distance
t=time
So v= 422/3
v =140.667m/s
Answer:
It is A. Because charged particles of solar wind ignite different gases in Earth's atmosphere.
Explanation:
Since the solar wind from the sun is too radioactive for humans (they would die), once the charged particles hit the earth's atmosphere it shows its color. Every element has its own color and once it hits the atmosphere it really starts to show.
