What is the Bohr Model?

Back

The Bohr Model is a representation of the atom that depicts electrons orbiting the nucleus in defined energy levels.

Front

What is the maximum number of electrons in the 1st energy level of a Bohr Model?

Back

2 electrons.

Front

What are isotopes?

Back

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

Front

How many valence electrons does an Oxygen atom have?

Back

6 valence electrons.

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 mass number of an atom?

Back

The mass number is the total number of protons and neutrons in the nucleus of an atom.

Front

What is the significance of valence electrons?

Back

Valence electrons determine how an atom can bond with other atoms and are crucial for chemical reactions.

Front

What is the electron configuration of Argon?

Back

1s² 2s² 2p⁶ 3s² 3p⁶.

Front

How do you determine the number of neutrons in an atom?

Back

Subtract the atomic number from the mass number.

Front

What is the relationship between energy levels and electron distance from the nucleus?

Back

Higher energy levels are further from the nucleus and can hold more electrons.
