How many electrons can be held in the third energy level?

How many electrons can be held in the third energy level?

Note: The third energy level can actually hold up to 18 electrons, so it is not really filled when it has 8 electrons in it.

How many electrons can the first energy level 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

What is the 2nd energy level?

Energy Levels of Electrons

Energy Level	Energy
2	–3.4 eV
3	-1.51 eV
4	-.85 eV
5	-.54 eV

How many electrons can the second and third levels 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.

How many electrons can fit in the 4th energy level?

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 4th Shell hold?

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.

What is the maximum that can occupy the 2nd energy level?

The maximum number of electrons in the second principal energy level is eight. This electron shell contains only two sublevels, the s sublevel and the p sublevel. S sublevels only have a single orbital, meaning they can only hold two electrons.

Is 2s the highest energy?

(By inference, sodium has a 2s orbital energy that is even more negative.) Therefore, H atom has the highest energy for its 2s orbital by analogy.

What elements has 2 energy levels?

Electrons

Atomic Number	Element	Energy Levels or “shells”
2	Helium (He)	2
3	Lithium (Li)	2
4	Beryllium (Be)	2
5	Boron (B)	2

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 can the 5th energy level hold?

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 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 can each level hold?

There can be two electrons in one orbital maximum. The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max.

Why are there 18 electrons in the 3rd energy level?

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.

Why can the third energy level hold 18 electrons?

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. In this sense the third shell can hold a total of 18 electrons۔

What is the 3rd energy level?

The third principal energy level will have one s sublevel orbital, three p sublevel orbitals, and five d sublevel orbitals. Each orbital can contain a maximum of two electrons. This means the s sublevel can only have two electrons while the p sublevel can have six electrons and the d sublevel can have 10 electrons.

Is the third energy level full with 7 electrons?

Two is the maximum number of electrons for the level so the other electrons will have to go in higher energy levels. The n=2 level can hold up to eight electrons so the next 8 electrons will go in the n=2 level. The remaining 7 electrons can go in the n=3 level since it holds a maximum of 8 electrons.
