Question: What Element Has The Electron Configuration 1s 2s 2p 3s 3p?

What element is 3s2?

sulfurAccording to the periodic table, this element is sulfur..

What is SPDF rule?

s, p, d, f and so on are the names given to the orbitals that hold the electrons in atoms. These orbitals have different shapes (e.g. electron density distributions in space) and energies (e.g. 1s is lower energy than 2s which is lower energy than 3s; 2s is lower energy than 2p). (image source)

Which element has the following ground state electron configuration 1s 2s 2p?

The element with a ground-state electron configuration of: 1s22s22p63s2 is Magnesium, Mg.

How many electrons are present in an atom with its 1s 2s 2p 3s 3p subshells filled?

The answer is 18 electrons. That’s the element that has got a stable electron configuration. That means that its subshells are completely filled with electrons and its last electrons fill p-subshell. So the element must be a p-block element from the last, 18th group of the Periodic Table of Elements.

How many orbitals are in 3p?

There are nine orbitals in the n = 3 shell. There is one orbital in the 3s subshell and three orbitals in the 3p subshell.

What element is 1s2 2s2 2p6 3s2 3p6 4s2 3d7?

Copper (Co)The electron configuration for Copper (Co) is: 1s2 2s2 2p6 3s3 3p6 4s2 3d7. A chemist would shorten this notation to just “3d7” – calling Copper by the subshell of highest energy that contains any electrons.

What element has 3 electrons in the 2p sublevel?

What is 1s 2s and 2p for orbitals?

At the first energy level, the only orbital available to electrons is the 1s orbital, but at the second level, as well as a 2s orbital, there are also orbitals called 2p orbitals. A p orbital is rather like 2 identical balloons tied together at the nucleus.

How many electrons are needed to fill 1s?

2 electrons1s will be filled first, with the maximum of 2 electrons. 2s will be filled next, with the maximum of 2 electrons. 2p will be filled next, with the maximum of 6 electrons. Continue until no any electrons left.

What is 1s 2s 2p 3s 3p?

The order of the electron orbital energy levels, starting from least to greatest, is as follows: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p. Since electrons all have the same charge, they stay as far away as possible because of repulsion. … For example, the 2p shell has three p orbitals.

Which element has the electron configuration of 1s 2 2s 2 2p 6 3s 2 3p 4?

Why is 2s lower than 2p?

In atoms with more than one electron, 2s is lower in energy than 2p. An electron in a 2s orbital is less well shielded by the other electrons than an electron in a 2p orbital. (Equivalently, the 2s orbital is more penetrating.) The 2s electron experiences a higher nuclear charge and drops to lower energy.

What element has the electron configuration 1s?

The order is summarized under the diagram. FIGURE 5.9 The arrow shows a second way of remembering the order in which sublevels fill.

How many electrons are in each 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. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.

How many electrons are in 2p?

6 electronsThe 2s subshell holds a maximum of 2 electrons, and the 2p subshell holds a maximum of 6 electrons.

What is the next atomic orbital in the series 1s 2s 2p 3s 3p?

The order of the electron orbital energy levels, starting from least to greatest, is as follows: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p.

What does 1s 2s 2p mean?

The superscript is the number of electrons in the level. … The number in front of the energy level indicates relative energy. For example, 1s is lower energy than 2s, which in turn is lower energy than 2p. The number in front of the energy level also indicates its distance from the nucleus.
