Electrons and the Periodic Table Review

This type of ion has a positive charge.

• anions

• cations

• isotope

• octet

How does a cation end up with a positive charge?

• It gains protons.

• It loses protons.

• It gains electrons.

• It loses electrons.

This type of ion has a negative charge.

• anions

• cations

• isotope

• octet

How does a anion end up with a negative charge?

• It gains protons.

• It loses protons.

• It gains electrons.

• It loses electrons.

What rule says that electrons will enter equal energy orbitals before pairing with a second electron in the same orbital?

• Hund's Rule

• Aufbau Principle

• Pauli Exclusion Principle

• Electron Configuration

This principle states that electrons in same orbital must have opposite spins.

• Hund's Rule

• Aufbau Principle

• Pauli Exclusion Principle

• Electron Configuration

This is a method for showing the distribution of electrons in the atom.

• Hund's Rule

• Aufbau Principle

• Pauli Exclusion Principle

• Electron Configuration

This principle says that electrons fill from the lowest energy orbitals and then fill the higher energy orbitals.
