Question

this will be graded, so make sure you understand all the concepts before making an attempt. write the number of valence electrons for the element below. element valence electrons k the periodic table of the main groups is pictured above (transition elements are not shown). the seventh - period elements that are shown as half gray are not well characterized, and their electron configurations are currently unknown.

Explanation:

Step1: Locate the element in the periodic table

Element \( K \) (Potassium) is in Group I of the periodic table.

Step2: Determine valence electrons based on group

Elements in Group I have 1 valence electron.

Answer:

1
