TEK 5A, 5B, 6D STUDY GUIDE

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 identity of the element.

Front

Which subatomic particle determines the identity of an element?

Back

The proton determines the identity of an element.

Front

What are isotopes?

Back

Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons.

Front

What is the significance of the periodic table in chemistry?

Back

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

Front

What are nonmetals?

Back

Nonmetals are elements that are poor conductors of heat and electricity and are typically found on the right side of the periodic table.

Front

What is a characteristic of halogens?

Back

Halogens are poor conductors of heat and electricity and are highly reactive nonmetals.

Front

What happens to the properties of an element when it is cut?

Back

The properties of the element remain the same; cutting does not change the chemical identity of the material.

Front

What is the relationship between protons and electrons in a stable atom?

Back

In a stable atom, the number of protons is equal to the number of electrons.

Front

What are alkali metals?

Back

Alkali metals are highly reactive metals found in Group 1 of the periodic table.

Front

What are alkaline earth metals?

Back

Alkaline earth metals are reactive metals found in Group 2 of the periodic table.
