Groups and Families Periodic Table

Front

What indicates the number of valence electrons in an atom on the periodic table?

Back

The group number (e.g., 1A, 2A) indicates the number of valence electrons.

Front

What are groups 3 - 12 on the periodic table called?

Back

Transition metals.

Front

Which group of elements is known for being the least reactive?

Back

Noble gases.

Front

Which element has fewer valence electrons than Aluminum (13)?

Back

Cesium (55) has 1 valence electron.

Front

Which element reacts similarly to Lithium (3) with water?

Back

Rubidium (37) reacts similarly to Lithium.

Front

What is the general trend of reactivity in alkali metals as you move down the group?

Back

Reactivity increases as you move down the group.

Front

What are the characteristics of noble gases?

Back

Noble gases are colorless, odorless, and mostly unreactive due to having a full valence shell.

Front

What is the significance of the periodic table's group number?

Back

The group number indicates the number of valence electrons and similar chemical properties.

Front

What are halogens known for?

Back

Halogens are highly reactive nonmetals with seven valence electrons.

Front

What is the difference between metals and nonmetals in terms of conductivity?

Back

Metals are good conductors of electricity, while nonmetals are poor conductors.
