Tonder Bohr Model/Periodic Table FLASHCARD

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have eight valence electrons, achieving a stable electron configuration.

Front

Who created one of the first periodic tables using atomic mass?

Back

Dmitri Mendeleev.

Front

What is the atomic number of an atom?

Back

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

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals, often found along the 'stair-step' line on the periodic table.

Front

What is the charge of an atom with equal protons and electrons?

Back

The charge is 0, meaning the atom is neutral.

Front

What are valence electrons?

Back

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

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 are the main groups of the periodic table?

Back

The main groups include alkali metals, alkaline earth metals, transition metals, halogens, and noble gases.

Front

What is an ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net charge.

Front

What is the difference between metals and nonmetals?

Back

Metals are typically shiny, conductive, and malleable, while nonmetals are usually dull, insulative, and brittle.
