CHEM Test 3 (12th) 21-22

The closer from the nucleus, the more energy the orbital has

• True

• False

Quantum numbers can be calculated only to the most external electron

• True

• False

An Orbital is a

• Region in space around the nucleus where the probability of finding the e^- is the least

• Region in space around the nucleus where the e^- is most likely to be found

• None of the above

It is possible to consider orbitals as probability electron clouds

• True

• False

• "s" orbital

• "p" orbital

• "d" orbital

Choose the correct one

• The "p" orbtial is always separated in 3 suborbitals

• In the atom, the three suborbitals are joined together

• None of the above

Choose the correct one

• It is known the exact position of the e^- in the electonic cloud

• It is unknown the exact position of the e^- in the electonic cloud, but we know is inside that region

• None of the above

The shapes of the orbitals (s,p,d,f) are the result of the resolution of the Schrödinger's Wave Model

• True

• False

State the differences between Bohr and Schrödinger's Atomic Model

Why is it important to study the Schrödinger Atomic Model?
