swyk: periodic trends
match the key term to its definition
the amount of energy required to remove an electron
electron affinity
ionization energy
electronegativity
atomic radius
the ability of an atom to gain electrons
the ability of an atom to hold electrons close to the nucleus
the size of the atom

Explanation:

• Ionization Energy: It is defined as the amount of energy required to remove an electron from an atom. This is a fundamental concept in understanding atomic behavior and chemical reactions.
• Electron Affinity: This is the ability of an atom to gain electrons. It plays a crucial role in determining how atoms form bonds (e.g., in ionic bonding where one atom donates and another accepts electrons).
• Electronegativity: It represents the ability of an atom to hold electrons close to the nucleus. High electronegativity means an atom has a strong pull on electrons in a chemical bond (e.g., in polar covalent bonds).
• Atomic Radius: As the name suggests, it is the size of the atom. Atomic radius trends (e.g., decreasing across a period due to increased nuclear charge pulling electrons in) are important in understanding atomic properties and periodic trends.

Answer:

• "The amount of energy required to remove an electron" matches with Ionization Energy.
• "The ability of an atom to gain electrons" matches with Electron Affinity.
• "The ability of an atom to hold electrons close to the nucleus" matches with Electronegativity.
• "The size of the atom" matches with Atomic Radius.
