Question

read the passage and use the diagram to answer the next two questions. the following figure shows the bond formation of sodium chloride which is a compound commonly known as table salt. select the answer that shows the numbers in the correct order to complete the sentence. a sodium atom has valence electron(s). a chlorine atom has valence electron(s). one; seven eleven; seventeen seven; seventeen one; eleven

Explanation:

Step1: Recall the definition of valence electrons

Valence electrons are the electrons in the outermost shell of an atom.

Step2: Analyze the sodium atom

Looking at the sodium (Na) atom diagram, the outermost shell has 1 electron. Sodium has an atomic number of 11, and its electron configuration is \(1s^{2}2s^{2}2p^{6}3s^{1}\). The outermost (valence) shell (\(n = 3\)) has 1 electron.

Step3: Analyze the chlorine atom

For the chlorine (Cl) atom, the outermost shell has 7 electrons. Chlorine has an atomic number of 17, and its electron configuration is \(1s^{2}2s^{2}2p^{6}3s^{2}3p^{5}\). The outermost (valence) shell (\(n=3\)) has \(2 + 5=7\) electrons.

Answer:

one; seven
