How many valence electrons can shell 3 have?
5 valence electrons
The third shell is the outer valence shell, so it has 5 valence electrons. The number of electrons in each shell becomes more complicated as more electrons are added because there are more subshells being used and because the shell start to fill out of order.
What element has 3 valence electrons and 3 shells?
Aluminium has a total of 3 electronic shells where 3rd shell is the outermost shell. The electronic configuration of Aluminium is given as Al – [2,8,3]. Hence, aluminium is an element retaining 3 valence electrons in its third shell.
Is it 8 or 18 electrons in third shell?
Each shell can contain only a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on.
Does indium have 3 valence electrons?
There are 3 valence electrons in indium specifically at the 5s and 5p orbitals.
Which group has 3 electron shells?
A lithium atom, for example, has three electrons. It has two in the first shell and one in the second shell….Electron shells.
| Energy shell | Maximum number of electrons |
|---|---|
| Third | 8 |
What element has 3 electrons in outer shell?
Metal
The correct answer is Metal. Metal has 1 to 3 electrons in its outermost shell. Metals usually have 1, 2, or 3 electrons in their valence shell. A valence shell means the outermost shell of an atom containing the valence electrons.
Why does the 3rd energy level hold 18 electrons?
A s orbital, a set of (3)p orbitals and a set of (5)d orbitals form the 3rd subshell. Each orbital carries 2 electrons and you can actually find that 18 electrons can be shot in. This is because it is the 3rd shell’s full power and it does not say the order in which the electrons are filled.
Can you have 18 electrons in its third shell?
So the third shell can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons. Each subshell can hold a different number of electrons.
What is the 3rd energy level?
The third principal energy level has one s orbital, three p orbitals, and five d orbitals, which can each hold up to 10 electrons. This allows for a maximum of 18 electrons. The fourth and higher levels have an f sublevel in addition to the s, p, and d orbitals.
