Front

What is nuclear fusion?

Back

Nuclear fusion is a process where two lighter atomic nuclei combine to form a heavier nucleus, releasing energy in the process.

Front

What is nuclear fission?

Back

Nuclear fission is a process where a heavy atomic nucleus splits into two or more lighter nuclei, along with the release of energy.

Front

What is the trend of atomic radius in the periodic table?

Back

Atomic radius decreases from left to right across a period and increases down a group.

Front

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

What is the trend of electronegativity in the periodic table?

Back

Electronegativity increases from left to right across a period and decreases down a group.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

What is the trend of ionization energy in the periodic table?

Back

Ionization energy increases from left to right across a period and decreases down a group.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

How does temperature affect activation energy?

Back

As temperature increases, the proportion of collisions that can overcome the activation energy for a reaction also increases.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves of energy that travel through space and include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
