Reading Periodic Tile & Calculating Mass

Front

What is the atomic number of an element?

Back

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

Front

How many electrons does a neutral atom have?

Back

A neutral atom has the same number of electrons as protons.

Front

What is the atomic mass of an element?

Back

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

Front

What is the chemical symbol for an element?

Back

The chemical symbol is a one or two-letter abbreviation used to represent an element on the periodic table.

Front

What are neutrons?

Back

Neutrons are neutral particles found in the nucleus of an atom, contributing to the atomic mass.

Front

What is the role of electrons in an atom?

Back

Electrons are negatively charged particles that orbit the nucleus and are involved in chemical bonding.

Front

How do you calculate the number of neutrons in an atom?

Back

The number of neutrons can be calculated by subtracting the atomic number from the atomic mass.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What is a valence electron?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is an isotope?

Back

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons.
