How many orbitals can the 4th shell hold?
Orbitals and Electron Capacity of the First Four Principle Energy Levels | Principle energy level (n) Type of sublevel Number of orbitals per level(n2) | 4 s 16 | p | d |

How many electrons are in 4s?
Principal Energy Level (n) sublevels total electrons | 1 1s 2 | 2 2s 2p 8 | 3 3s 3p 3d 18 | 4 4s 4p 4d 4f 32 |

Why is 3rd shell 8 or 18?
In this sense the third shell
can hold 8 electrons
. 4s2 not the third shell, but the next 10 electrons go into the 3d orbitals that are part of the third shell but shown on the fourth shell level. … So the third shell can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons.
What are the 4 types of sublevels?
Named for their energy sublevels, there are four types of orbitals:
s, p, d, and f
. Each orbital type has a unique shape based on the energy of its electrons.
What is the 2 8 8 rule in chemistry?
There is a 2-8-8 rule for these elements.
The first shell is filled with 2 electrons, the second is filled with 8 electrons, and the third is filled with 8
. You can see that sodium (Na) and magnesium (Mg) have a couple of extra electrons. They, like all atoms, want to be happy.
Is it 8 or 18 electrons in 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.
Why does the third shell have 8 electrons?
Energy shell Maximum number of electrons | First 2 | Second 8 | Third 8 |

Which sublevel is lowest in energy?
The lowest energy sublevel is always the
1s sublevel
, which consists of one orbital. The single electron of the hydrogen atom will occupy the 1s orbital when the atom is in its ground state.
What are the six sublevels called?
To distinguish between the different s sublevels, we call them
1s, 2s, 3s, and 4s
. The p sublevels are called 2p, 3p, and 4p. There is no d sublevel until the 3rd level. The d sublevels are called 3d and 4d.
Which Subshell has the highest energy?
- Ans: The simple answer is because 4s orbital is lower in energy than 3d orbital when they are empty.
- Qn: But isn’t principle quantum n=3 supposed to have lower energy than n=4?
Why is the maximum number of valence electrons 8?
The number of valence electrons in any atom of a Representative Element corresponds to its Group Number. … As all Group VIII members have a filled valence shell,
they have no tendency to react in oxidation-reduction reactions
.
Why do atoms want 8 electrons?
The rule of 8 or the Octet rule
Does oxygen give or take electrons?
An oxygen atom needs
two extra electrons
to fill its outer shell. … This gives the oxygen the extra electrons it needs. And, the hydrogen atoms get what they need, too. They share the oxygen’s electrons to get one extra electron each.
How many electrons are in third shell?
Energy shell Maximum number of electrons | First 2 | Second 8 | Third 8 |

Why does the number of electrons in the third shell suddenly change from 8 to 18?
Explain why the number of electrons in the third shell suddenly changes from 8 to 18 between the element calcium, Ca, and Gallium, Ga?
Because there are 10 euments between Ca and Ga. 8
. On the Table of Electron Shells handout complete the bottom section to describe the ion properties of each group.
