How many electrons can be held in the third orbital?
Each shell can only hold a certain number of electrons. The first shell can hold two electrons, while the second shell can hold eight (2 + 6) electrons. The third shell can hold 18 (2 + 6 + 10), and so on. The general rule is that the nth can hold up to 2(n2) of electrons.
What number of electrons can each orbital contain?
two electrons
Why does the third shell contain 8 electrons? In its lowest state, the third shell can hold 8 electrons. However, it can hold 18 electrons when including the higher-energy 3d electrons.
The question is also, how many electrons does the fourth orbital contain?
The fourth energy level contains 18 electrons. The fourth level of the periodic tables includes the 4s 3d, and 4p orbitals. The 4p orbital contains 6 electrons.
What is the maximum number possible electrons in the 3s orbital?
It follows that 1 atomic orbital can reside in the 3s Sublevel x 2 electrons/orbital = 2. The 3p sublevel can contain 3 atomic orbitals x 2 electrons/orbital = 6.

Why is 3rd shell 8 or 18?
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. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
Why are there only 2 electrons in the first shell?
This first shell has only one subshell (labeled 1s) and can hold a maximum of 2 electrons. This is why there are two elements in the first row of the periodic table (H & He). Because the first shell can only hold a maximum of 2 electrons, the third electron must go into the second shell.
Why do shells start with K?
He noticed that atoms appeared to emit two types of X-rays. As it turns out, the K type X-ray is the highest energy X-ray an atom can emit. It is produced when an electron in the innermost shell is knocked free and then recaptured. This innermost shell is now called the K-shell, after the label used for the X-ray.
What does an orbital diagram look like?
Orbital diagrams are pictorial descriptions of the electrons in an atom. Three rules are useful in forming orbital diagrams. According to the Auf Bau Principle, each electron occupies the lowest energy orbital. You jump up a little bit in energy and we get the 2s orbital that make it the 2p sublevel.
How is Valency calculated?
The valency of an atom is equal to the number of electrons in the outer shell if that number is four or less. Otherwise, the valency is equal to eight minus the number of electrons in the outer shell. Once you know the number of electrons, you can easily calculate the valency.
How many electrons can 5f hold?
Each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
How many electrons does p orbital hold?
6 electrons
What is a Subshell?
A subshell is a subdivision of electron shells separated by electron orbitals. Subshells are labelled s, p, d, and f in an electron configuration.
How many Subshells are in the N 5 shell?
For n = 5, the possible values of l = 0,1,2,3,4. These numbers correspond to s, p, d, f and g orbitals. Now, s has 1 subshell, p has 3, d has 5, f has 7 and g has 9. Thus, total number of subshells = 25.
Why are there 8 electrons in the outer shell?
The eight- electrons stability of an atom is stemmed from the stability of the noble gases or the elder name inert gases, which had long been known as unreactive or noble. However, this rule is justified for elements of second row in the periodic table, which their outermost- shell capacity is 8 electrons.
How many electrons can 2s hold?
The second shell has two subshells, s and p, which fill with electrons in that order. The 2s subshell holds a maximum of 2 electrons, and the 2p subshell holds a maximum of 6 electrons.
How many Subshells are in the N 3 shell?
three subshells
How many orbitals are there in n 3?
nine orbitals
Why are there only 8 electrons in the outer shell?
The octet rule is a chemical rule of thumb that reflects the observation that elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas. All four of these electrons are counted in both the carbon octet and the oxygen octet.
Why can there only be 8 valence electrons?
This is because of the quantum nature of the atoms, where electrons are organized in shells: the first (named the K shell) has 2 electrons, the second (L-shell) has 8, the third (M shell) has 18. Atoms combine into molecules by trying in most cases to have valence electrons entirely filling a shell.
Why does the 3rd period have 8 elements?
Why the third period in periodic table have 8 elements only? According to the Aufbau's Principle (the building up principle) there can be only EIGHT elements that satisfy this. This is because the S orbital of the fourth shell sits at a lower energy level (closer to the nucleus) than the d orbital of the third shell.
