When do d orbital start getting filled?
after the s orbital of the next highest energy level
What is the number of unpaired electrons in a lithium atom?
Lithium atoms contain one unpaired electron. Two of the three total electrons in a lithium atom are paired in its lowest energy s orbital, which can contain only two.
Which orbital electron has the highest energy?
I would think the s orbital, because it is closer to the nucleus, and because the outer energy level holds more energy than the inner ones.
What atom is represented in the following orbital diagram 1s2s2p?
The next highest energy electron orbital after 3p is the 4s orbital, after which comes the 3d and then 4p orbitals.
The valence electrons of which element has the highest energy hydrogen lithium sodium or potassium?
To determine this look at the periodic table. The larger the atom, the farther its valence electrons are from the nucleus. Therefore, potassium's valence electrons have the highest energy.
What Alkali metal has the highest ionization energy?
lithium
Which is the highest energy orbital for a silicon atom?
3p is the highest "occupied" orbital of an "unexcited" neutral Silicon atom.
When do d orbital start getting filled?
after the s orbital of the next highest energy level
What is the highest energy occupied molecular orbital for N 22?
sigma 2p
Which Alkali metals would undergo the least exothermic reaction with chlorine?
Most likely lithium since it has a the highest ionization energy than the others.
When do orbitals start getting filled?
after the s orbital of the next highest energy level

Which orbital electron has the highest energy?
I would think the s orbital, because it is closer to the nucleus, and because the outer energy level holds more energy than the inner ones.
What is the relative energy in the s orbital?
The relative energy of the s orbital is lower than that of the p, d, and f orbitals. In a multi-electron atom, the s orbital has a lower energy because it experiences a stronger attraction to the positive nucleus due to its spherical shape and higher electron density. Therefore, electrons are more likely to occupy the s orbital before filling higher-energy orbitals.
What has a second ionization energy level of 1577?
The element that has the highest second ionization energy is Li. When you remove the first electron from Li you are down to the 1s orbital. They are harder to remove because they are closest to the nucleus.
Why is the ionization energy of beryllium is higher than lithium?
Ionization energy represents the energy required to remove electrons from an atom. The first and second ionization energies are relatively small because the lectrons must be removed from the 2s orbital. For the third ionization energy the electron must be removed from the 1s orbital which has less energy than the 2s, and so requires much more energy to be removed.
What atom is represented in the following orbital diagram 1s2s2p?
The next highest energy electron orbital after 3p is the 4s orbital, after which comes the 3d and then 4p orbitals.
