Periodic table and trends

Front

What is the most reactive group of non-metals?

Back

Halogens are the most reactive group of non-metals.

Front

What does it mean for elements to be in the same period on the periodic table?

Back

Elements in the same period have the same number of electron shells.

Front

Which Group 2 element has the lowest ionization energy?

Back

Barium (Ba) has the lowest ionization energy among Group 2 elements.

Front

What is electronegativity?

Back

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

Front

Which element is not part of the Alkali metal family?

Back

Hydrogen (H) is not part of the Alkali metal family.

Front

What are Alkali metals?

Back

Alkali metals are the elements in Group 1 of the periodic table, known for being highly reactive.

Front

What is the trend in ionization energy across a period?

Back

Ionization energy generally increases across a period from left to right.

Front

What is the trend in electronegativity down a group?

Back

Electronegativity generally decreases as you move down a group in the periodic table.

Front

What are Noble gases?

Back

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

Front

What is the significance of the periodic table's groups?

Back

Elements in the same group have similar chemical properties due to having the same number of valence electrons.
