Question

draw the lewis dot structures for...
carbon selenium rubidium

Explanation:

Lewis dot structures represent valence electrons as dots around the element symbol.

• Carbon (C): It has 4 valence electrons. The Lewis dot structure is \(\cdot\!\!\cdot\!C\!\!\cdot\!\!\cdot\).
• Selenium (Se): It has 6 valence electrons. The Lewis dot structure is \(\cdot\!\!\cdot\!Se\!\!\cdot\!\!\cdot\) with two additional dots (total 6).
• Rubidium (Rb): It has 1 valence electron. The Lewis dot structure is \(Rb\cdot\).

Answer:

• Carbon: \(\cdot\!\!\cdot\!C\!\!\cdot\!\!\cdot\)
• Selenium: \(\cdot\!\!\cdot\!Se\!\!\cdot\!\!\cdot\) (with two more dots for a total of 6)
• Rubidium: \(Rb\cdot\)
