Which elements have 2 electrons in the 4s sublevel?
The elements that have 2 electrons in the 4s sublevel are calcium (Ca) and scandium (Sc).
What number on the periodic table indicates the energy level of an atoms valence electrons?
The number beside the letter represents the energy level. The letter represents the sub level. The exponent represents the number of electrons in the sub level. So in the case of: 1s^2 1 is the energy level; S is the sub level; ^2 is the number of electrons in the sub level.
What energy level are the outermost electrons of vanadium?
The outermost electrons of vanadium are located in the 4s and 3d orbitals. These electrons generally occupy the 4s orbital before filling the 3d orbitals.
How many electrons completely fill the fourth energy level?
1s = 2 + 2s & p = 8 + 3s & p & d = 18 + 4s & p & d & f = 32 { close to binary } + = Total is 60 electrons.
How many unpaired electrons in As?
Like all the elements in the nitrogen family, Arsenic has 5 valence electrons. The five electrons inhabit the 4s and 4p orbitals: As: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3

When comparing the energy of an electron in the 3d sub-level to that of an electron in the 4s sublevel of the same atom?
They are both capable of holding a maximum of 10
What energy level are the outermost electrons of vanadium?
The outermost electrons of vanadium are located in the 4s and 3d orbitals. These electrons generally occupy the 4s orbital before filling the 3d orbitals.
Why in periodic table 3 period has 8 elements rather than 18?
That is because the 4s level (which places those elements in period 4) is fist filled with 2 electrons before the 3d level is on terms to be filled with 10 electrons (with a higher energy level than the ground level of both 4s orbits of K and Ca). This 3d-block is called the transition metals (nr.21-30, Sc to Zn)
Why does 4s orbital start filling while 3p orbital is empty?
The electrons fill in the lowest energy orbital that is available. Electrons in the 4s orbital have a lower energy level than electrons in the 3p orbital, so the 4s orbitals are filled with electrons first.
Why does an element lose 4S electrons before 3D electrons?
An element loses 4s electrons before 3d electrons because the 4s orbital has a higher energy level (n value) than the 3d orbital. When an atom loses electrons to form a cation, it tends to lose the electrons from the outermost shell first, which in this case is the 4s orbital.
What is the 4S orbital?
The 4s orbital is a type of atomic orbital that is part of the fourth energy level in an atom. It has a spherical shape and can hold up to 2 electrons. The 4s orbital is lower in energy than the 3d orbital in the periodic table.
Which energy level would the valence electrons be located on the manganese atom?
The valence electrons of manganese are located in the 4s and 3d energy levels.
How many electrons completely fill the fourth energy level?
1s = 2 + 2s & p = 8 + 3s & p & d = 18 + 4s & p & d & f = 32 { close to binary } + = Total is 60 electrons.

What is similar about 3s and 4s sublevels?
Both the 3s and 4s sublevels are part of the s orbital, meaning they have spherical symmetry. They both contain electrons with similar energy levels, with the 4s sublevel having higher energy than the 3s sublevel.
