Review The Atomic Model

Front

What is the Bohr model of the atom?

Back

The Bohr model is a representation of the atom that depicts electrons orbiting the nucleus in fixed paths or energy levels.

Front

What charge do neutrons carry?

Back

Neutrons carry no charge.

Front

What are noble gases?

Back

Noble gases are a group of elements that are colorless, odorless, and have low chemical reactivity. They exist as monatomic gases at room temperature.

Front

What is an anion?

Back

An anion is a negatively charged ion that has more electrons than protons.

Front

Which element loses 2 electrons to achieve an octet?

Back

Magnesium loses 2 electrons to achieve a stable octet configuration.

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 element's identity.

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 8 electrons, leading to greater stability.

Front

What is the difference between an ion and a neutral atom?

Back

An ion is an atom that has gained or lost electrons, resulting in a charge, while a neutral atom has an equal number of protons and electrons.

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 role of protons in an atom?

Back

Protons determine the atomic number and identity of an element, and they contribute to the positive charge of the nucleus.
