But what do the superscripts 2 after the “s” and 6 after the “p” refer to? These refer to the number of electrons in that particular orbital/shell . So, for neon, there are 2 electrons in the 1s shell, 2 electrons in the 2s shell, and 6 electrons in the 2p shell.
What does the 3 in 3s2 mean?
sulfure: 1s2,2s2,sp6,3s2,3p4. what does the 3 in 3s2 refer to. 3rd energy level . flaws with modern view of the atom. our model can change at any time new info is discovered, making it more accurate.
What do the numbers in 3s2 symbolize?
The first number is the energy level. ... For example, the first energy level only contains an s sub-shell while the second energy level contains both an s sub-shell and a p sub-shell. The number in superscript is the number of electrons in a sub-shell . Each sub-shell can hold only a certain number of electrons.
What does 4s2 mean?
When someone writes [Ar] 4s2 3d6, they are writing in order of energy (orbitals fill in order of energy). When they write [Ar] 3d6 4s2, they are writing in order of location, that is, n=3 orbitals before n=4 orbitals. This is useful because when atoms LOSE electrons, they lose them according to their location.
What does 2p mean in chemistry?
Each orbital can hold up to two electrons . The three p orbitals, therefore can accommodate up to six electrons. When one electron is accommodated by the 2p orbitals it is written 2p 1 ; five electrons would be written 2p 5 .
What element is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6?
So, an antimony atom with charge +2 has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p1.
What element is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3?
| A B | 1s2 2s2 Be | 1s2 2s2 2p3 N | 1s2 2s2 2p6 3s2 3p6 4s2 3d3 V | 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3 As |

What does the 1 in 1s 2 mean?
question_answer Answers(4)
Example: 1s 2 2s 2 2p 2 : It means there are 2- electrons in first energy level s-subshell and 2-electrons 2 nd energy level s- sub shell and 2-electrons in 2 nd energy level p-sub shell . Energy level.
What does the 1 represent in 1s 2?
The 1 refers to the principal quantum number . And the 2 is the number of electrons in it, two being the maximum. It is an electron configuration- a way to find out the valence electrons, blocks, groups and periods of elements in the periodic table.
Which atom has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d2?
So, an antimony atom with charge +2 has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p1.
What is 1s2 2s2 2p6 3s2 3p6 4s2 3d6?
1s2 2s2 2p6 3s2 3p6 4s2 3d6. Highest energy electron. Element = Iron .
What is XE 6s2?
Barium has the noble gas configuration [Xe]6s2.
What happens if electrons have the same spin?
Because electrons of the same spin cancel each other out , the one unpaired electron in the atom will determine the spin. There is a high likelihood for either spin due to the large number of electrons, so when it went through the magnetic field it split into two beams.
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.
Why are there 3 2p orbitals?
For example, the 2p shell has three p orbitals. If there are more electrons after the 1s, and 2s orbitals have been filled, each p orbital will be filled with one electron first before two electrons try to reside in the same p orbital. ... This is the way electrons move from one electron orbital to the next.
What is 1s 2s 2p?
For example, the electron configuration of the neon atom is 1s 2 2s 2 2p 6 , meaning that the 1s, 2s and 2p subshells are occupied by 2, 2 and 6 electrons respectively. Electronic configurations describe each electron as moving independently in an orbital, in an average field created by all other orbitals.
