How many electrons are needed in the outer energy levels for the atom to be stable?

Stability isn't determined by the first energy level. The only atom with less than two is hydrogen. It is a very stable atom...reactive in that it will attach to anything, but it will always be hydrogen. The atoms that readily decay (the radioactive ones) all have full first orbitals.

Atoms are stable when their outer energy level is full, which typically means having 8 electrons for most elements (except hydrogen and helium which only need 2). This full outer shell configuration is known as the octet rule, which helps atoms achieve a more stable electron configuration similar to the noble gases.

How many electrons are called are needed in the outer energy level of most atoms for the atom to be stable?
Most atoms are stable when they have a full outer energy level, which typically consists of 8 electrons. This is known as the octet rule. However, some smaller atoms, such as hydrogen and helium, are stable with only 2 electrons in their outer energy level.
Does xenon have five energy levels?
No, xenon has multiple energy levels due to its electron configuration. Xenon has a total of 54 electrons, which occupy different energy levels within the atom. It is a noble gas with a full outer shell of electrons, leading to a stable configuration.
When atoms share electrons to fill their outermost energy levels they form?
When atoms share electrons to fill their outermost energy levels, they form covalent bonds. In a covalent bond, electrons are shared between atoms to achieve stable electron configurations.
Why energy levels important in the periodic table?
Energy levels in the periodic table indicate the relative stability and reactivity of an element. Elements with filled energy levels are more stable, while those with incomplete energy levels are more likely to undergo chemical reactions to achieve a stable configuration. Understanding energy levels helps predict the chemical behavior and properties of elements on the periodic table.
How many electrons are required in the outer energy level for most elements to be stable?
Most elements require 8 electrons in their outer energy level to be stable, except for hydrogen and helium which require only 2. This is known as the octet rule, where atoms tend to gain, lose, or share electrons to achieve a full outer energy level of 8 electrons.
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.
How many electrons are need in the outer energy levels of most atoms for the atom to be chemically stable?
8 are traditionally needed in the valence shell.

How many electrons are needed in the outer energy level to make H stable?
Only 1 electron needed to make H stable.
What is the group number for elements that have a stable number of electrons in their energy levels?
They r noble gases which have stable valance shell and grotp no. 18
Which group in the periodic table has a stable number of electrons in their outer energy levels?
noble gases or group 1
When atoms share electrons to fill their outermost energy levels they form?
When atoms share electrons to fill their outermost energy levels, they form covalent bonds. In a covalent bond, electrons are shared between atoms to achieve stable electron configurations.
What happen when electron change energy level?
When an electron changes energy levels in an atom, it absorbs or emits energy in the form of a photon. This photon can have a specific wavelength corresponding to the energy difference between the initial and final energy levels of the electron. This process is fundamental to the emission and absorption of light in atoms.
Do metals and non metals become more chemically stable when they fill or empty their outermost energy levels?
When they fill their outermost energy levels. Metals will WANT more electrons and Non-Metals will have EXTRA electrons to give. So in a way, Metals will actually fill their outermost energy levels while Non-Metals will empty them; all with the goal of having a FULL valency shell which is stable. This is the basis for ionic bonding.
Do noble gases have the maximum number of electrons in their outer energy level?
Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.
How many electrons are required in the outer energy level for most elements to be stable?
Most elements require 8 electrons in their outer energy level to be stable, except for hydrogen and helium which require only 2. This is known as the octet rule, where atoms tend to gain, lose, or share electrons to achieve a full outer energy level of 8 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.
