Arrangement of Electrons in Atoms & The Period Law

Front

What is the arrangement of electrons in an atom?

Back

Electrons are arranged in energy levels or shells around the nucleus of an atom, with each level having a specific capacity for electrons.

Front

What is the maximum number of electrons in the first energy level?

Back

The first energy level can hold a maximum of 2 electrons.

Front

What is the maximum number of electrons in the second energy level?

Back

The second energy level can hold a maximum of 8 electrons.

Front

What is the maximum number of electrons in the third energy level?

Back

The third energy level can hold a maximum of 18 electrons.

Front

What is the Pauli Exclusion Principle?

Back

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers.

Front

What are quantum numbers?

Back

Quantum numbers are a set of numerical values that describe the unique quantum state of an electron in an atom.

Front

What is the shape of the s orbital?

Back

The s orbital has a spherical shape.

Front

What is the shape of the p orbital?

Back

The p orbital has a dumbbell shape.

Front

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

Which element has the highest electronegativity?

Back

Fluorine (F) has the highest electronegativity.
