Answer:
a. A beta particle has a negative charge. d. A beta particle is a high-energy electron.
Explanation:
Identify the correct descriptions of beta particles.
a. A beta particle has a negative charge. YES. A beta particle is originated in the following nuclear reaction: ¹₀n ⇒ ¹₁H + ⁰₋₁e (beta particle.)
b. A beta particle contains neutrons. NO. It is a electron originated in the nucleus.
c. A beta particle is less massive than a gamma ray. NO. Gamma rays don't have mass while a beta particle has a mass which is half of one thousandth of the mass of a proton.
d. A beta particle is a high-energy electron. YES. Beta particles are nuclear originated hig-energy electrons.
Answer:
Option D is Correct answer
Answer:
C) The student and desk have to be in contact to apply the force.
Explanation:
I am pretty sure :)
Polar bonds are formed between atoms of different electronegativities.
A compound can be treated like an element when balancing chemical equations when : A. when there is no change to the atoms in the compound
If they remain together during the reaction, you can treat a compound as a singe atom.
hope this helps
