Question

in this performance task you will answer four questions. the electron configurations of two unknown atoms are shown. electron configuration atom x atom y based on the electron configuration of each atom, what is the number of valence electrons for each atom? atom x = 11 atom y = 17 atom x = 1 atom y = 1 atom x = 1 atom y = 7 atom x = 10 atom y = 10

Explanation:

Step1: Identify valence electrons definition

Valence electrons are electrons in the out - most shell.

Step2: Count for Atom X

Atom X has 1 electron in its out - most shell.

Step3: Count for Atom Y

Atom Y has 7 electrons in its out - most shell.

Answer:

Atom X = 1, Atom Y = 7
