determine which of the following has the lowest electronegativity. write out the full name. ta or cs
Answer
Explanation:
Step1: Recall electronegativity trend
Electronegativity increases across a period and decreases down a group in the periodic table. Cesium (Cs) is an alkali - metal and tantalum (Ta) is a transition metal. Cs is further to the left and lower in the periodic table compared to Ta.
Step2: Determine the element
Since Cs is more metallic and has a lower electronegativity based on periodic trends, Cs has the lower electronegativity.
Answer:
Cesium
