How many electrons are in the outermost shell of an atom?

eight electrons
This is known as the octet rule, which states, with the exception of the innermost shell, that atoms are more stable energetically when they have eight electrons in their valence shell, the outermost electron shell.

Why there are 8 electrons in the outer shell?

The maximum capacity of a shell to hold electrons is 8. The shells of an atom cannot accommodate more than 8 electrons, even if it has a capacity to accommodate more electrons. This is a very important rule called the Octet rule.

Which is the outermost shell?

This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons. In general, atoms are most stable, least reactive, when their outermost electron shell is full.

How many electrons are in the outer shell of Group 7?

seven electrons
The Group 7 elements – fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (At) – have seven electrons in the outer shell.

How many electrons are there in 4th shell?

32
This model breaks down at the n=3 shell because each shell has subshells. There are 4 subshells, s, p, d, and f. Each subshell can hold a different number of electrons….Search form.

n=	Shell	Maximum Number of Electrons
1	1st Shell	2
2	2nd Shell	8
3	3rd Shell	18
4	4th Shell	32

Which is outermost shell?

How do you find outermost shell?

So we can use the column or group of an element to determine the number of electrons in its outermost shell, sometimes referred to as valence electrons. Elements from the fourth column of the periodic table, like carbon, have four electrons in their outermost electron shell or four valence electrons.

Which element has 8 protons 8 neutrons 8 electrons?

oxygen
An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999.

How many electrons can the n=1 shell of an orbital hold?

An s-orbital holds 2 electrons. Thus n=1 shell can hold two electrons. The n=2 (second)shell has: The 2s orbital

What is the maximum number of electrons that can fit?

In my textbook, it says that the maximum number of electrons that can fit in any given shell is given by 2n². This would mean 2 electrons could fit in the first shell, 8 could fit in the second she… Stack Exchange Network

What is the number of electrons in the nth shell?

If you mean “all orbitals with the same value of the principal quantum number” – number of electrons is much higher. In general, nth shell holds up to 2n2 electrons on all subshells (orbitals – s, p, d, f…).

How many electrons can the outermost shell of a covalent compound hold?

it says: “the first and inner most shell has a capacity for 2 electrons, the outermost shell has a capacity for 32 electrons”. I thought the outermost shell always had a maximum capacity of 8.
