CH101/Ison Summer 2 Ch3 Worksheet Name: _________, ________ last, first Valence electrons: Rules: s-block: highest energy s electrons are valence d-block: highest energy s and d electrons are valence p-block: highest energy s and p electrons are valence Ionization energy (IE) is the energy required to remove the outmost electron from an atom or ion in the gaseous state. Smaller atoms have higher IE Electronegativity (EN) is a measure of the ability of an atom to attract bonding electrons. Smaller atoms have higher EN. Exception: Noble gases have filled valence orbitals and are therefore not electronegative. General observations: - Larger atoms have high energy valence orbitals, low EN and IE - Smaller atoms have low energy valence orbitals , high EN and IE Comparing energy levels: Assign the appropriate energy level to each of the following atoms and fill in the electrons: B, O
