An atom with 10 electrons must have how many shells?
An atom with 10 electrons will have 2 electron shells. The first shell can hold up to 2 electrons, and the second shell can hold up to 8 electrons.
How many electron shells does an atom of oxygen have?
An oxygen atom has two shells. The first contains two electrons, and the second contains six electrons.
How many number of electron shells does fluorine atom have?
A fluorine atom has 2 electron shells. The first shell can hold up to 2 electrons, and the second shell can hold up to 8 electrons, giving a total of 10 electrons for a fluorine atom.
How many shells are there in Nitrogen?
there are two shells of electrons in the nitrogen atom that actually have electrons in them, nitrogen has two electrons in the first shell, the S orbital, and five in the outer shell, the P orbital. this causes nitrogen to have a valence shell with five electrons.
How many electron shells would at atom have if it had 16 electrons?
An atom with 16 electrons would have 3 electron shells. The first shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, and the third shell can hold up to 8 electrons.
How many shells have an atom?
It depends on the atomic number. If the atomic number is 5 it has five protons neutrons and electrons. The electrons make up the shells so the first shell is two electrons then the second 8 but there is only five so its an unstable atom.
16 electrons need how many shells?
16 electrons would fill up the first four shells in an atom: 2 electrons in the first shell, 8 electrons in the second shell, 4 electrons in the third shell, and 2 electrons in the fourth shell.
How many electrons are there in a first shell of a neutral neon atom?
Neon atom number 10: first shell (K) : 2 electrons second shell (L): 8 electrons all shells being filled up completely
How many electron shells are around the nucleus of the berylluim atom?
There are 2 electron shells around the nucleus of a beryllium atom. The first shell can hold a maximum of 2 electrons, and the second shell can hold a maximum of 8 electrons. Since beryllium has 4 electrons, 2 electrons will be in the first shell and the remaining 2 electrons will be in the second shell.
How many shells are there in selenium atom?
A selenium atom typically contains 34 electrons distributed in different shells around the nucleus. The electrons are arranged in energy levels or shells, with the first shell holding a maximum of 2 electrons, the second shell holding up to 8 electrons, the third shell holding up to 18 electrons, and the fourth shell holding up to 6 electrons for selenium.
How many electrons shells does Platinum have?
Platinum is in the 6th period, meaning its atom has 6 energy shells. It is in Group 10 and has 78 electrons.
