If an atom gains an electron, what overall charge will it have?
Oliga [24]

Answer:

The atom will have a negative charge.

Explanation:

Electrons are subatomic particles with a negative charge, protons are subatomic particles with a negative charge, and neutrons have no charge. When a neutral atom's balance is disrupted by an extra electron, the atom  becomes negatively charged.

radioisotope actinium 225 has half life of 10 days, I begin with 16 kg of this isotope, how much will remain after 40 days?
Igoryamba
N(t)=N_{0}(\frac{1}{2})^\frac{t}{\tau_{_\frac{1}{2}}}}\\\\
N_{0}=16kg\\
t=40days\\
\tau_{_\frac{1}{2}}}=10days\\\\\\
N(t)=16kg*(\frac{1}{2})^{\frac{40}{10}}=16kg*\frac{1}{16}=1kg

How many neutrons are in the nucleus of an atom that has an atomic mass of 36 and an atomic number of 25?
elixir [45]

Answer:

Neutrons = 11

Explanation:

To get the number of neurons an element has you have to subtract the number of protons from the atomic mass of that element.

The number of protons is equal to the atomic number of that element.

Atomic number = Number of Protons

So the number of protons is 25

Neutrons = Atomic mass - Number of Protons

Neutrons = 36 - 25

Neutrons = 11
