How many electrons will there be in each atom of lithium?
Each atom of lithium will have 3 electrons. Two electrons will fill the 1s orbital, and the third electron will occupy the 2s orbital, following the electron configuration of 1s^2 2s^1.
How many electrons occupy the second orbital?
8
How many electron orbitals does helium have?
How many atoms / electron clouds does helium have ?
Why is the s-block called s-block?
The elements in the s-block have their last electrons in their electron configuration in the s-orbital.
A spherical electron cloud surrounding an atomic nucleus best represents what?
A spherical electron cloud surrounding an atomic nucleus best represents the probability distribution of finding electrons in an atom. This model is described by quantum mechanics and helps to visualize the regions where electrons are most likely to be found in an atom.
Which orbital do calciums outermost electrons occupy?
Calcium's outermost electrons occupy the 4s orbital.
Can two electrons occupy a single orbital?
of course they can. They have to be of opposite spin and two is the maximum number that can occupy one orbital.
Which electron is on average further from the nucleus an electron in a 3p orbital or an electron in a 4p orbital?
An electron in a 2s orbital is on average closer to the nucleus.
The sp3d2 atomic hybrid orbital set accommodates how many electron PAIRS?
there r 2 electrons in the s orbital, their r 6 electrons in p orbital , their r 10 electron's in the d orbital and 14 electrons in f orbital.
How many unparied electrons does fluorine have?
Fluorine in its elemental stage has 1 unpaired electron. ( 2p5 orbital has one unpaired electron in 2p orbital)
What is the theory that within a sub level electrons prefer to occupy their own orbital?
Hund's rule is the principle that within a sublevel, electrons prefer to occupy orbitals singly and with parallel spins before pairing up. This minimizes electron-electron repulsions and stabilizes the atom.
Paired electrons are represented by what dots?
An electron pair are two electrons which occupy the same orbital in an atom or molecule. Paired electrons are represented by two dots.
