The process of isotopes breaking down and emitting particles, such as alpha or beta, to form a new substance.
Answers
Answer: The process is called as nuclear decay process.
Explanation:
Nuclear reaction are defined as the reactions in which nucleus of an atom is involved.
Isotopes under decay process in order to attain stability.
Unstable isotopes known as parent isotopes undergo various decay processes to form stable isotopes known as daughter isotopes.
The various decay processes are:
- Alpha decay: In this process, alpha particle is released.
- Beta decay: In this process, beta decay is released.
- Gamma decay: In this process, gamma decay is released.
Hence, the process is called as nuclear decay process.

Non-metals tend to have high ionization energy and low electronegativity.
Answers
Answer:
By definition, the first ionization energy of an element is the energy needed to remove the outermost, or highest energy, electron from a neutral atom in the gas phase. The process by which the first ionization energy of hydrogen is measured would be represented by the following equation.

The first step is to identify all the elements and how many atoms of that element there are on either side of the equals sign.
When you do this you will get,
1 Cu 1
1 Ag 1
1 N 2
3 O 6
Next step is to make sure that all the elements are the same on both sides. This is mostly trial and error until you balance both sides.
The solution to the equation would be:
Cu + 2AgNO3 = Cu(NO3)2 + 2Ag
So now if you check your elements, you will get the following:
1 Cu 1
2 Ag 2
2 N 2
6 O 6
As you can see all the elements are equal on both sides, so the equation is balanced.

Explanation:
When a chemical equation has equal number of atoms on both reactant and product side then it is known as a balanced equation.
For example,
Number of atoms on reactant side are as follows.
K = 1
Cl = 1
O = 3
Number of atoms on product side are as follows.
K = 1
Cl = 1
O = 2
Hence, to balance this equation we multiply by 2 on the reactant side and multiply KCl by 2 and
by 3 on the product side.
Therefore, the balanced chemical equation is as follows.
