When an atom emits a beta
particle from the nucleus, the nucleus only has one more proton and one less
neutron and this will make the atomic mass number remains unchanged while the
atomic number increases by 1.

Answer:
Condensation occurs when a gas changes into a liquid.
Explanation:
Condensation is when a gas becomes a liquid. It happens when a gas, like water vapor, cools down. Matter can exist in three different states: solid, liquid or gas.
Answer:True But matter can take up much space and is stronger than density and gravity
Explanation: Gravity is like a force that just pull on objects now if you get down to the magnets well magnetism is the strongest force on earth that could be connected through the core
<u>Answer:</u> The correct answer is Option D.
<u>Explanation:</u>
Atomic mass of an atom is defined as the sum of number of neutrons and number of protons that are present in an atom. It is represented as 'A'.
Atomic number = Number of protons + Number of neutrons
We are given:
Number of protons = 6
Number of neutrons = 6
Number of electrons = 6
Atomic mass = 6 + 6 = 12
Hence, the correct answer is Option D.
