Periodic Table Basics Review

Front

What is the periodic table?

Back

A tabular arrangement of chemical elements, organized by increasing atomic number, electron configuration, and recurring chemical properties.

Front

What is an element?

Back

A pure substance that cannot be broken down into simpler substances by chemical means, consisting of atoms with the same number of protons.

Front

What is the atomic number?

Back

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

Front

What are valence electrons?

Back

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

Front

How many periods are there in the periodic table?

Back

There are 7 periods in the periodic table.

Front

What are groups in the periodic table?

Back

Vertical columns in the periodic table that group elements with similar chemical properties.

Front

What is the significance of the position of an element in the periodic table?

Back

The position indicates its properties, such as reactivity, state at room temperature, and the number of valence electrons.

Front

What are metals?

Back

Elements that are typically shiny, good conductors of heat and electricity, and malleable.

Front

Where are nonmetals located on the periodic table?

Back

On the right side of the periodic table.

Front

What is a metalloid?

Back

An element that has properties of both metals and nonmetals, found along the zig-zag line on the periodic table.
