Chemistry Semester 1 Review

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. It is a key concept in understanding chemical bonding.

Front

Which element has a higher electronegativity than arsenic (As)?

Back

Carbon (C) has a higher electronegativity than arsenic.

Front

What is the position of Magnesium (Mg) in the periodic table?

Back

Magnesium (Mg) is located in period 3, group 2 of the periodic table.

Front

What does the Pauli's Exclusion Principle state?

Back

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

Front

What is the charge of a lithium atom that loses 1 electron?

Back

The charge on a lithium atom that loses 1 electron is +1.

Front

Which element has the smallest ionization energy in Period 6?

Back

Cesium (Cs) has the smallest ionization energy in Period 6.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

What is the Aufbau Principle?

Back

The Aufbau Principle states that electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What is Hund's Rule?

Back

Hund's Rule states that electrons will fill degenerate orbitals singly before pairing up.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.
