Answer:
the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport.
Explanation:
<u>Answer:
</u>
When the outer electron shell is full in an element, this creates a Noble gas.
<u>Explanation</u>:
Noble gases are the elements that belong to group 18 in the periodic table. Noble gases are also called as inert gases. The outermost shell of the noble gases are fully filled by electrons. Due to this the noble gases don’t react with any other elements and remain isolated.
There are 6 noble gases in the periodic table. They are helium (He), Argon (Ar), Neon (Ne) Krypton (Kr), Radon (Rn) and Xenon (Xe). Noble gases conduct electricity. They are fluorescent, odorless and colorless. Noble gases are used a maintain stable elements in a constant and safe environment.
The basic type of vaccines are:
nucleic acid vaccines
subunit vaccine
live, attenuated vaccine
An easy, secure, and reliable method of preventing hazardous infections before you are exposed to them is vaccination. It boosts your immune system and builds up your body's natural defenses against particular illnesses.
Your immune system is trained by vaccinations to produce antibodies, exactly as it does when it is exposed to a disease. However, because vaccinations only include dead or weakened versions of bacteria or viruses, they do not really cause the disease or increase your chance of developing its symptoms.
In order to create immunity, vaccines act in conjunction with your body's natural defenses. Your immune system reacts when you receive a vaccination.

Answer:
Attractive forces between particles.
Explanation:
Solids keep its shape and volume because of strong attractive forces between the particles.
Other options are incorrect:
Because there is no space between solid particles.
The shape of solid does not depend upon type of particles present.
The shape and volume of solids not depend upon the volume and shape of container.
Properties of solids:
Solids have definite volume and shape.
In solids molecules are tightly pack and very close to each other.
Their melting and boiling point are every high.
The densities of solids are also very high as compared to the liquid and gas.
There are very strong inter molecular forces are present between solid molecules.
