Question

complete the table below. for example, in the first row decide whether sc³⁺ is a cation or anion. in the second row, write the symbol for the ion that an atom of cesium is mostly likely to form and then decide what type of ion it is.

element	most likely ion
scandium	sc³⁺	cation anion
cesium		cation anion
sulfur		cation anion
beryllium		cation anion
chlorine		cation anion

Explanation:

Step1: Determine cesium ion

Cesium is in Group 1. It loses 1 electron to form an ion. So the ion symbol is $Cs^+$ and it is a cation.

Step2: Determine sulfur ion

Sulfur is in Group 16. It gains 2 electrons to form an ion. So the ion symbol is $S^{2 -}$ and it is an anion.

Step3: Determine beryllium ion

Beryllium is in Group 2. It loses 2 electrons to form an ion. So the ion symbol is $Be^{2+}$ and it is a cation.

Step4: Determine chlorine ion

Chlorine is in Group 17. It gains 1 electron to form an ion. So the ion symbol is $Cl^-$ and it is an anion.

Answer:

element	most likely ion
scandium	$Sc^{3+}$	cation
cesium	$Cs^+$	cation
sulfur	$S^{2 -}$	anion
beryllium	$Be^{2+}$	cation
chlorine	$Cl^-$	anion
