Well it depends upon which element you are talking about
Eg flourine atom has 9 protons and electrons normally configuration will be 2,8,1
But if u r talking about a stable fluorine electron, configuration will be 2,8
This happens since the outermost octate of fluorine is not filled completely so it is not stable in it's structure so it loses the 1 extra electron in it's last octate and becomes stable gaining a negative charge
Ultimately no. Of levels vary from element to element
What else can I help you with?
How many electrons does a stable sodium atom have?
Sodium has 11 electrons.
What is the most stable state of an atom called?
The most stable state of an atom is called the ground state. This is when the electrons occupy the lowest energy levels available to them.
What causes an atom to be stable and unstable?
An atom is stable when its nucleus has a balanced ratio of protons and neutrons, and when its electrons are in filled energy levels. An atom is unstable when it has an imbalance of protons and neutrons in the nucleus, leading to radioactive decay in an attempt to reach a more stable configuration.
How many electrons are there in a iron atom?
There are 26 electrons in an iron atom. Each neutral iron atom has a total of 26 electrons occupying various energy levels or electron shells.
What causes an atom to be stable?
An atom becomes stable by gaining or loosing electrons.
An atom with it's electrons in the lowest possible energy level is said to be?
An atom with its electrons in the lowest possible energy level is said to be in its ground state. The ground state is the most stable configuration for an atom, with electrons occupying the available energy levels starting from the lowest.
How many energy levels in a neutral atom of xenon and how many electrons would be left over?
A neutral atom of xenon has 6 energy levels, with 54 electrons occupying those levels. Xenon has 54 electrons in total, so no electrons would be left over in a neutral xenon atom.
What makes the electrons more stable?
Electrons are more stable when they are in lower energy levels, closer to the nucleus of an atom. They are also more stable when they are paired with another electron in the same orbital, following the Pauli exclusion principle. Additionally, atoms are more stable when their outermost energy levels are filled with electrons, resulting in a full valence shell.
What is the neutral atom that has its first two energy levels filled has 6 electrons in its third energy level and has no other electrons?
The neutral atom with the specified electron configuration has 10 electrons in total. This atom is neon (symbol: Ne), which has a total of 10 electrons and has its first two energy levels filled with 2 and 8 electrons, respectively, while the third energy level contains 6 electrons.
How does a atom become stable?
When the atom has 8 valence electrons.
Why do valence electrons determine the reactivity of an atom?
The valence electrons are the outermost electrons. In an atom, its lower energy levels have been filled and are therefore stable. But, except for the noble gases, the valence energy level is not filled, and therefore not stable. So atoms must undergo chemical reactions in order to fill their valence shells and become stable. They can do this by sharing electrons, transferring electrons, or by forming a sea of electrons shared by all the atoms.
How many many electrons are needed in the outer energy levels of most atoms for the atom to be chemically stable?
Generally speaking, it would be 8 electrons, but there are many exceptions.
