Why all atom have 2 electron in first shell not more or less?
Actually, there is only one electron in a hydrogen atom, which has the atomic number 1. The existance of exactly two electrons in the innermost shell can be described by Shrodinger's Wave Equation. According to the Wave Equation, there is only one atomic orbital existing in the principal quantum number 1 energy level which is also known as 1s. Any atomic orbital can hold 2 electrons at most and it is the reason that every atom other than hydrogen have exactly 2 electrons in their innermost energy level.
Why 2 electrons are present in s orbital?
It is not the orbital that holds more electrons. All orbitals can hold a maximum of 2 electrons.However, the p-subshell can hold more electrons than the s-subshell. This is because the s-subshell is only made of 1 orbital, and 1 x 2 = 2, therefore it can only hold 2 electrons. The p-subshell is made of 3 orbitals, and 3 x 2 = 6, so it can hold a maximum of 6 electrons.So, a p-subshell can hold more electrons than an s-subshell because it is made up of more orbitals. It is not the orbitals that hold more electrons.
Do atom orbitals contain thousands of electrons or just a few electron?
If you look at a periodic chart, you will see that each element has a number. That number gives the number of protons and electrons that each element contains. There are limits to the number of electrons that any orbital can contain. The orbitals are labeled: s, p, d, f, g, h, i, k. The first two atoms in the periodic table, Hydrogen and Helium, only have an s orbital. The s orbital holds two electrons. When the s orbital is full, as with Helium, it can not react with anything else. Helium is inert. The next row in the periodic table contains the p orbital. When the p orbital is full, as in Neon, then it can not react. If you look at the periodic table, the orbitals can hold more electrons and each element can hold more orbitals. If it becomes possible to create an element with several hundred protons, the orbitals could hold many electrons.
Why in nb the 4d orbital should not cantain 3 electrons?
Half and fully filled orbitals are more stable that other configurations. Because of this, the d orbital will take an extra electron from the s orbital in order to make it more stable. The actual configuration would be 5s1 4d4.
An electron in a 3s orbital penetrates into the region occupied by core electrons more than electrons in a 3p orbital?
This is due to the difference in the effective nuclear charge experienced by electrons in different orbitals. Electrons in the 3s orbital have a higher effective nuclear charge, which leads to greater penetration into the region occupied by core electrons compared to electrons in the 3p orbital. This results in the 3s electrons being more shielded from the core electrons in the atom.
What is the atomic orbital after 4s?
After the 4s orbital, the next orbital in order of increasing energy is the 3d orbital. The 3d orbital has a more complex shape compared to the s and p orbitals and can hold up to 10 electrons.
How many electrons can be held in the fourth orbital?
The fourth orbital, which is the 4d orbital, can hold up to 10 electrons. This orbital has a higher energy level than the 3d orbital and can accommodate more electrons. Each orbital can hold a maximum of 2 electrons per subshell (s, p, d, f).
How do you draw the lewis dot diagram for beryllium?
In your nucleus you should include the number of protons and neutrons. The number of protons can be found in the periodic table as the atomic number. To get the number of neutrons, subtract the protons from the atomic mass. Next, you draw the orbitals, and their respective electrons. Remember the number of electrons in each orbital. 1st orbital-2 electrons 2nd orbital- 8 electrons 3rd orbital- 18 electrons
Why can a p sublevel hold 6 electrons while the s sublevel can hold no more than 2 electrons?
The p sublevel consists of three orbitals, each of which can hold up to 2 electrons. This totals to a maximum of 6 electrons in the p sublevel. In contrast, the s sublevel consists of only one orbital, which can hold a maximum of 2 electrons due to the rules of electron configuration in an atom.
How many electrons are present in an orbital formed from the overlap of two different atomic orbitals?
2 electrons. Each orbital can only have a maximum of 2 electrons according to quantum mechanics and more specifically Paulis theory... The over lap is occurring because each orbital only has 1 electron so the over lap when finished will have 2.

Why 2 electrons are present in s orbital?
It is not the orbital that holds more electrons. All orbitals can hold a maximum of 2 electrons.However, the p-subshell can hold more electrons than the s-subshell. This is because the s-subshell is only made of 1 orbital, and 1 x 2 = 2, therefore it can only hold 2 electrons. The p-subshell is made of 3 orbitals, and 3 x 2 = 6, so it can hold a maximum of 6 electrons.So, a p-subshell can hold more electrons than an s-subshell because it is made up of more orbitals. It is not the orbitals that hold more electrons.
What is the molecular orbital that can be occupied by two electrons of a covalent bond?
The molecular orbital that can be occupied by two electrons of a covalent bond is the bonding molecular orbital. This orbital forms by the overlap of atomic orbitals in a constructive manner, leading to a decrease in energy when two electrons are placed in it.
How many electrons can go into a orbital?
In an atom, electrons are in "shells", the first shell is around the center of the atom and holds a maximum of 2 electrons. Each subsequent shell out, will hold a maximum of 8 electrons. there is no maximum number of shells.
How many electrons can go in each orbital?
S can hold no more than 2 P can hold up to 6 D can hold up to 10 F can hold up to 14
The 3s orbital differs from 2s orbital in that it is?
The 2s orbital and 3s orbital both have the same spherical shape and can hold a maximum of two electrons of opposite spin. They only differ because the 3s orbital is further out from the nucleus than the 2s orbital, thus the 3s orbital has a higher energy value.
What must be true about electrons sharing the same atomic orbital?
The Pauli exclusion principle would require that an electron sharing the same orbital would have to have opposite spin from the other particle in the pair. They therefore have different spin quantum numbers of +(1/2) and -(1/2)
