Question

instructions fill in the arrows below with the following terms. increasing electronegativity, increasing metallic character, increasing atomic radius, increasing nonmetallic character, increasing reactivity, decreasing atomic radius

Explanation:

• Atomic radius: Increases down a group (as more electron shells are added) and decreases across a period (due to increasing nuclear charge pulling electrons closer).
• Electronegativity: Increases across a period (as atoms have a greater tendency to attract electrons) and generally decreases down a group (as the atomic size increases, reducing the pull on electrons).
• Metallic character: Increases down a group (atoms lose electrons more easily) and decreases across a period (atoms gain electrons more easily).
• Non - metallic character: Opposite of metallic character, so it decreases down a group and increases across a period.
• Reactivity: For metals, reactivity increases down a group (easier to lose electrons). For non - metals, reactivity is highest near the top right (excluding noble gases).

Answer:

• Left - hand vertical arrows (pointing down): increasing atomic radius, increasing metallic character.
• Top - right diagonal arrow (pointing up - right): increasing electronegativity, increasing non - metallic character.
• Bottom horizontal arrow (pointing right): decreasing atomic radius.
• Bottom horizontal arrow (pointing left): increasing metallic character.
