12 Week Key Terms Reteach Tutorial

Front

What is a noble gas electron configuration?

Back

Front

What is a covalent bond?

Back

A covalent bond is the sharing of electron pairs between atoms, allowing them to achieve stability.

Front

Which elements are classified as alkali metals?

Back

Alkali metals are found in Group 1 of the periodic table and include elements like Lithium, Sodium, and Potassium.

Front

How do you calculate the mass number of an atom?

Back

The mass number is calculated by adding the number of protons and neutrons in the nucleus of an atom.

Front

What is the trend in electronegativity across a period?

Back

Electronegativity increases as you move from left to right across a period in the periodic table.

Front

What is the definition of an electron configuration?

Back

An electron configuration is the distribution of electrons in an atom's orbitals, indicating how electrons are arranged around the nucleus.

Front

What are the main characteristics of alkali metals?

Back

Alkali metals are highly reactive, have one electron in their outermost shell, and are soft and shiny.

Front

What is the significance of the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, leading to greater stability.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electron pairs.

Front

What is the role of neutrons in an atom?

Back

Neutrons contribute to the mass of an atom and help stabilize the nucleus by offsetting the repulsive forces between protons.
