Periodic Trends

Front

What happens to atomic size as you move across a period in the periodic table?

Back

Atomic size decreases because atoms have more protons, which increases the positive charge and pulls electrons closer to the nucleus.

Front

What is ionization energy?

Back

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

Front

Which group in the periodic table is known for having high reactivity and includes elements like fluorine and chlorine?

Back

Halogens.

Front

How does electronegativity change across a period?

Back

Electronegativity increases from left to right across a period.

Front

What is the trend in atomic size as you move down a group in the periodic table?

Back

Atomic size increases because atoms have more energy levels.

Front

What is the general trend of ionization energy as you move down a group?

Back

Ionization energy decreases as you move down a group.

Front

What are alkali metals?

Back

Alkali metals are the elements in Group 1 of the periodic table, known for being highly reactive and having one electron in their outermost shell.

Front

What is the significance of noble gases in the periodic table?

Back

Noble gases are known for their lack of reactivity due to having a full valence shell of electrons.

Front

Define electronegativity.

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

What is the trend of electronegativity as you move down a group?

Back

Electronegativity decreases as you move down a group.
