Explain why this statement is false: Ba is larger than Sr because the last electron added has a higher value of angular momentum quantum number (l).
Ba is larger than Sr. this part is correct
But 2nd part makes the statement wrong
angular momentum quantum number (l) is 0 for both since electrons are added in s orbital for both.
This is the reason the statement is false
The correct reason for larger size of Ba is because of a greater shell in Ba

D Question 10 Why is Bra smaller atom than As? Br is actually larger than As because it has more protons. As is larger because it has more protons and electrons. Br has more protons to pull the electrons in closer. Br is smaller because it has less protons and electrons making it smaller. Br is actually larger than As because it has a larger atomic mass. Question 11 Explain why metals have lower ionization energy than nonmetals. No answer...

1. Which statement is true about the H-atom and explain why. a. The energy state does not depend on the azimuthal quantum number, 1 b. Energy levels become more widely separated as the principle quantum rumber, n, increases c. The total number of nodes in a wave function is equal to twice the quantum number, n d. The 3dxy orbital has 1 angular node and 1 radial node 2. There are many mathematical acceptable solutions to the Schrodinger equation for...
22. Select the correct statements below. L. An atom of chlorine is larger than sulfur because the addition of an electron increases the repulsions without an increase in attraction for the nucleus resulting in less screening. An atom of oxygen is smaller than an atom of carbon because the distance of the valence electrons remains the same while the attraction for the nucleus increases with increasing number of protons. III. An atom of potassium is smaller than an atom of...
