What does Aufbau's principle say about orbital diagrams?
you must fill in the lowest orbitals first before moving to the higher levels
what do the arrows in the orbital diagram represent
electrons
How can you say that sodium has a larger atomic radius than gallium (Ga) even though gallium has one more electron shell than sodium?
Gallium does have one more orbital, but it has over double the protons which means it has great control over that extra shell. In gallium, the protons are pulling those outer electrons more than sodium's protons are which causes the radius to be smaller than that of sodium.
What does the following mean:
Mg 2+
N 3-
N has gained 3 electrons
Draw the electron configuration for Sr 2+
1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10, 4p6
Describe Hund's rule for orbital diagrams
Hund says that before you place a second arrow in a sublevel, each sublevel must have at least one arrow
draw the orbital diagram for titanium
teacher can draw or you can google it
Why does fluorine have a great nuclear charge but a smaller radius than oxygen?
Fluorine has one more proton than oxygen which means it has more control over its outer electron which makes its atomic radius smaller
Krypton has a full valence electron shell which means it is happy. It does not want to attract any more electrons which means no electronegativity. But because krypton is happy, it wants to lose NO electrons, so the ionization energy is very high.
What element is described?
