How many electrons can the 2nd and 3rd energy levels hold?

How many electrons can the 2nd and 3rd energy levels hold?

Answer and Explanation: The number of electrons that the second level can hold is up to eight electrons (2+6). The first level/ shell can hold up to two (2). The third level/ shell can hold up to eighteen (2+6+10).

How many energy levels have electrons?

The atoms in the first period have electrons in 1 energy level. The atoms in the second period have electrons in 2 energy levels. The atoms in the third period have electrons in 3 energy levels. The atoms in the fourth period have electrons in 4 energy levels.

How many electrons can energy level 4?

The first energy level can hold up to 2 electrons, the second energy level can hold up to 8 electrons, the third energy level can hold up to 18 electrons, and the fourth energy level can hold up to 32 electrons.

How many electrons can the first 3 energy levels hold?

Questions and Answers

Energy Level (Principal Quantum Number)	Shell Letter	Electron Capacity
1	K	2
2	L	8
3	M	18
4	N	32

How many does the 2nd 3rd and 4th shell of electrons hold?

The first shell only has the s subshell ⟹ 2 electrons. The second shell has the s and p subshells ⟹ 2 + 6 = 8 electrons. The third shell has the s, p, and d subshells ⟹ 2 + 6 + 10 = 18 electrons. The fourth shell has the s, p, d, and f subshells ⟹ 2 + 6 + 10 + 14 = 32 electrons.

How many electrons does the 3rd Shell hold?

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.

Can all energy levels hold 8 electrons?

How many electrons can a given energy level hold? The maximum numbers of electrons possible for the first four energy levels are shown in the Figure above. For example, energy level I can hold a maximum of two electrons, and energy level II can hold a maximum of eight electrons.

How many electrons can the 2nd energy level hold?

The second shell can hold 8 electrons. The third shell can hold 32 electrons. Within the shells, electrons are further grouped into subshells of four different types, identified as s, p, d, and f in order of increasing energy.

How many electrons can the 7th energy level hold?

Explanation: The f subshell has a total of seven orbitals, and each orbital can hold two electrons, and so the f subshell can hold a total of 7⋅2=14 electrons.

How many electrons are in the 5th energy level?

The fifth energy level contains: 5s (which holds 2 electrons), 5p (which holds 6), 5d (holds 10), and 5f (holds 14) for a total of 32 electrons.

How much can the 4th energy level hold?

Thus, the fourth level can hold up to 32 electrons: 2 in the s orbital, 6 in the three p orbitals, 10 in the five d orbitals, and 14 in the seven f orbitals.

How many electrons can fill the 4th Shell?

Answer and Explanation: The fourth shell of an atom can hold a maximum of 32 electrons, depending on the element. There are four subshells – 4s, 4p, 4d, and 4f – that can hold a maximum of 2, 6, 10, and 14 electrons, respectively, for a total of 32.

Why is 3rd shell 8 or 18?

second and third periods can accommodate 8 and 18 electrons respectively. Since their outermost shells can contain only 8 electrons, there are only 8 elements in boththe periods.

How much can the 3rd energy level hold?

The maximum electrons present in a d-orbital is 10 electrons. So, the third principal energy level can hold maximum 18 electrons and contain one s-orbital, three p-orbital and five d-orbital.

What energy level has 10 electrons?

The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max.

How many energy levels can there be?

Explanation: Every atom has an infinite number of energy levels available, depending on how much energy has been absorbed. In the ground state, there are seven (known/most-often-seen) energy levels which may contain electrons.

Which energy level contains 50 electrons?

Maximum number of electron in an energy level (2n2)

Principal Energy Level (n)	sublevels	total electrons
2	2s 2p	8
3	3s 3p 3d	18
4	4s 4p 4d 4f	32
5	5s 5p 5d 5f 5g	50

Do electrons have energy levels?

Electrons spin and rotate around the outside of the nucleus. As the electrons circle the nucleus they travel at certain energy levels but can “jump” between different energy levels if they gain or lose energy.
