An orbital can have a maximum of two electrons that have different sets of the four quantum numbers (n, l, ml, ms).
The element with the lowest atomic number that contains 10 p electrons in the ground state is neon. Neon has an atomic number of 10, and in its ground state, it has 2 electrons in the 1s orbital, 2 electrons in the 2s orbital, and 6 electrons in the 2p orbital.
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.
it has 9 electrons atomic number= number of protrons and electrons and atomic mass-atomic number=neutrons
Not necessarily. The atomic number is the same amount as the protons found in a certain element. remember that the number of protons are equal to the number of electrons as well. EX - Calcium's atomic number is 20 so therefore there are 20 protons and 20 electrons in the element. The atomic number also helps you find any valence electrons EX- oxygen's atomic number is 8 so you have 2 electrons filling the 1st orbital and 6 filling the 2 orbital. but the 2nd orbital is supposed to have 8 electron so there are 6 valence electrons.

Neon is a non metal element. Atomic number of it is 10.
The orbital diagram for chromium with atomic number 24 would show two electrons in the 1s orbital, two electrons in the 2s orbital, six electrons in the 2p orbital, six electrons in the 3s orbital, two electrons in the 3p orbital, and four electrons in the 3d orbital. This configuration would follow the aufbau principle and Hund's rule.
The number of electrons is always the same as the atomic number. That gives you the number of protons and electrons. The atomic mass has nothing to do with it. What is the atomic number? That is your answer.
Just two, with opposite spin.
Orbitals don't contain elements. The elements each have specific orbitals based on the number of electrons it has. All of the elements have at least one s orbital. Hydrogen being the simplest element has one electron in the 1s orbital. The s orbital can contain a maximum of 2 electrons.
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
