Atomic Structure and Periodic Table

Front

What are noble gases?

Back

Noble gases are a group of inert gases in Group 18 of the periodic table that are not reactive under standard conditions.

Front

What is the atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

Which elements are found in Group 1 of the periodic table?

Back

Group 1 elements are known as alkali metals, which include lithium, sodium, potassium, rubidium, cesium, and francium.

Front

What is the significance of the zig-zag line on the periodic table?

Back

The zig-zag line on the periodic table separates metals from non-metals, with metals on the left and non-metals on the right.

Front

What are protons, neutrons, and electrons?

Back

Protons are positively charged particles, neutrons have no charge, and electrons are negatively charged particles found in an atom.

Front

What is the difference between metals and non-metals?

Back

Metals are typically shiny, malleable, and good conductors of heat and electricity, while non-metals are dull, brittle, and poor conductors.

Front

What is a period in the periodic table?

Back

A period is a horizontal row in the periodic table, indicating the number of electron shells in the elements.

Front

What is a group in the periodic table?

Back

A group is a vertical column in the periodic table, indicating elements that have similar chemical properties.

Front

What is the atomic mass?

Back

The atomic mass is the weighted average mass of an element's isotopes, measured in atomic mass units (amu).

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and non-metals, found along the zig-zag line on the periodic table.
