How many moles of gold are there in 4.54 x 10^22 atoms of gold

0.075moles

Explanation:

1 gold gives 6.022×10^23atoms

X gold gives 4.54×10^22 atoms

Cross multiply

6.022×10^x=4.54×10^22

Divide both sides by 6.022×10^23

X=0.075 moles

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
