Science 8- Intro to the Periodic Table Notebook Flashcard

Front

Subatomic particles with a positive charge

Back

Protons are subatomic particles found in the nucleus of an atom, carrying a positive electrical charge.

Front

What is the charge of a neutron?

Back

Neutrons have a neutral charge, meaning they carry no electrical charge.

Front

What does the number 7 represent on a periodic table square?

Back

The number 7 represents the atomic number, which indicates the number of protons in an atom of the element.

Front

How many neutrons are in Fluorine?

Back

Fluorine has 10 neutrons.

Front

What are the three main types of elements on the periodic table?

Back

The three main types of elements are metals, nonmetals, and metalloids.

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 a metalloid?

Back

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

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 an isotope?

Back

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