What atom can hold 18 electrons in its outer level?
No atom can hold 18 electrons in its outer energy shell - there is the valence rule, stating that the maximum for the outer shell is 8 electrons.
What do elements in the same group share common?
Number of valence electrons, that is, the number of electrons that the outer shell of an atom can hold. Ex. All halogens can have 7electrons in their outer shell. All gases have a full octet, eight electrons.
What is the number of electrons that can occupy the first shell of an atom?
The first shell can hold two electrons only.
How many places are there for electrons in the third shell of an atom?
The third shell of an atom can hold a maximum of 18 electrons. This shell consists of three subshells - s, p, and d - with each subshell being able to accommodate a certain number of electrons. The s subshell can hold up to 2 electrons, the p subshell can hold up to 6 electrons, and the d subshell can hold up to 10 electrons, totaling 18 electrons in the third shell.
What term is used for the electrons in the outermost shell?
there called valence electrons
What atom can hold 18 electrons in its outer level?
No atom can hold 18 electrons in its outer energy shell - there is the valence rule, stating that the maximum for the outer shell is 8 electrons.
How many electrons can the outer level of an atom hold?
an atom has different energy orbitals: s, p, d, and f. each orbital can hold two electrons. the outside energy or highest energy levels of electrons is called the valence shell or valence electrons. for an atom to be stable it wants the electron configuration for the valence shell to be "s2, p6." to answer your question the outer level of an atom can hold 8 electrons. it is called the valence shell.
How many electrons can the K shell of an atom hold?
The K shell of an atom can hold up to 2 electrons.
What do elements in the same group share common?
Number of valence electrons, that is, the number of electrons that the outer shell of an atom can hold. Ex. All halogens can have 7electrons in their outer shell. All gases have a full octet, eight electrons.
A Sodium atom has 1 electron in its outer shell which can hold 8 electrons. To achieve stability the sodium atom does what?

How many inner shell electrons in chlorine?
There are 3 shells total in the atom of Chlorine. The first shell has 2 electrons because the first shell of any atom can only hold up to a maximum of 2 electrons. The second shell holds 8 electrons because the second shell of any atom can only hold 8 electrons maximum. The third shell holds 7 electrons in the Chlorine atom, but the third shell of any atom can hold up to 18 electrons as a maximum.
What is the number of electrons that can occupy the second shell of an atom?
The second shell can hold eight electrons.
Why are the outermost electrons of an atom important?
An element's group is defined by the number of electrons on the outer shell. For instance, Lithium is in Group One because it contains one electron in its outer shell while Neon is in Group 0 because it has zero on its outer shell.
How many electrons are on the outer shell of lithium?
A lithium atom has one electron on the outer shell. This is because there is 2 electrons maximum on the inner shell, so there is one left over for the outer shell. Hope you understand now xx
Why is chlorine in period 3?
Chlorine is in period three because that is how many outer shells it has. One period is one shell... In the First outer shell you can only hold.. 2 electrons. Second outer shell can hold 10 electrons. Third outer shell can hold 18 electron. Protons + Electrons = Atomic Number Atomic Number - Atomic Mass = Number of Neutrons in Outer Shells
What is the number of electrons that can occupy the first shell of an atom?
The first shell can hold two electrons only.
Why do outer shells of atoms hold more electrons?
Because the shell can only hold eight electrons. check
