Periodic Table & Trends

Front

What are noble gases?

Back

Noble gases are a group of inert gases in Group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell.

Front

Which element has the highest ionization energy?

Back

Helium has the highest ionization energy among all elements, meaning it requires the most energy to remove an electron from its outer shell.

Front

What happens to electronegativity in Group 16 as you move down the group?

Back

Electronegativity decreases as you move down Group 16 in the periodic table.

Front

Which element has the highest electronegativity among W, X, Y, and Z?

Back

Element W has the highest electronegativity.

Front

How many valence electrons does Argon (Ar) have?

Back

Argon has 8 valence electrons.

Front

What is the periodic trend for atomic radius across a period?

Back

The atomic radius decreases as you move from left to right across a period due to increasing nuclear charge.

Front

What is the periodic trend for atomic radius down a group?

Back

The atomic radius increases as you move down a group due to the addition of electron shells.

Front

Define electronegativity.

Back

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

Front

What is the significance of the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, leading to greater stability.

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 valence electron.
