An atom that has 3 electrons in its second shell and a filled first shell will?
be stable because the first shell is filled with electrons, providing it with a stable configuration. The second shell having 3 electrons will also fulfill the octet rule, making the atom more stable.
An atom does not need any electrons if it has outermost shell?
An atom needs electrons in its outermost shell to be stable. The number of electrons in the outer shell determines the atom's chemical properties and reactivity. If an atom's outer shell is complete, it is considered stable and less likely to react with other atoms.
When is an atom most stable?
Answer When the outermost shell(valence shell) is filled the atom is to be most stable. First Shell: holds up to 2 electrons Second Shell: holds up to 8 electrons Third Shell: holds up to 18 electrons Fourth Shell: holds up to 32 electrons
How many electrons can fit in the third shell of an atom?
The third shell of an atom can hold a maximum of 18 electrons. The first shell can hold up to 2 electrons, the second shell up to 8 electrons, and the third shell up to 18 electrons based on the formula 2n^2, where n is the shell number.
How is cl- ion formed by the cl atom?
The Cl atom gains an electron from another atom, and electrons carry a 1- charge. The Cl atom does this because it has 7 outer shell electrons, which isn't very stable, while an outer shell of 8 electrons is stable.
How many electrons does an atom need in its outer shell to be stable?

Does an atom need 8 electrons in its outer shell to be stable?
YES!
If an atom has a stable number of electrons how can you tell?
If an atom has a stable number of electrons, it will have a full outer electron shell (valence shell). This full outer shell will typically have 2, 8, 18, or 32 electrons, depending on the period the atom is in. Atoms with full valence shells are considered stable because they are less likely to undergo chemical reactions to gain or lose electrons.
How many places are there for a electrons in the third sheel of an atom?
In the third shell of an atom, there are a total of 18 possible electron positions. This shell can hold up to 2n² electrons, where n is the principal quantum number of the shell. For the third shell (n=3), this calculation gives 2(3)² = 18 electrons. The third shell includes the s, p, and d subshells, which can accommodate these electrons.
What is the Electron shell arrangement of a Silicon Atom?
what is the arrangement of electrons in an atom of a silicon
How many electrons can the 3rd atom shell hold?
The third electron shell can hold a maximum of 18 electrons.
How are valence electrons related to stability?
Valence electrons are the outermost electrons in an atom, and they determine the atom's chemical properties. Atoms with a full valence shell of electrons tend to be stable because they have a lower energy state. Atoms will gain, lose, or share electrons to achieve a full valence shell, which increases their stability.
