Answer:
False.
Explanation:
Noble gasses are extremely unreactive. They are called 'noble' because they do not mix with almost any other element, save flouride. They all, except helium, have a complete first and second valence level, meaning ten total electrons. Because of this they are very stable and do not want to receive any electrons or give any.
Answer:
B.
Explanation:
I believe it is B, it could be C too.
I can’t do math right now but the formula is density = mass / volume
Answer: has zero mass
is an electron
has a -1 charge
is electromagnetic energy
Explanation:
A beta-particle is an electron emitted from the nucleus of an atom following the decay of a neutron into a proton. Beta rays are deflected by a magnetic field in a direction that indicates a negative charge, thus they are electromagnetic in nature.
The beta particle released is basically a electron with -1 charge and no mass.
General representation of beta particle in the form of given as
where,
Z represents Atomic number
A represents Mass number
X represents the symbol of an element
If you meant to say 100C, then yes this is True.
