How do you write electronic configuration?
Writing Electron Configurations. When writing an electron configuration, first write the energy level (the period), then the subshell to be filled and the superscript, which is the number of electrons in that subshell. The total number of electrons is the atomic number, Z.
What element has the electron configuration 1s22s22p63s23p2?
2 Answers. BRIAN M. The electron configuration 1s22s22p63s23p2 is the element Silicon.Which element has the electron configuration 2 8 2?
Magnesium is the element with the electronic configuration of 2,8,2 as its atomic number is 12, since the atomic number is the sum of all the electrons present in the electronic configuration.
What is the electron configuration for v2+?
1 Expert Answer In shorthand, the electron configuration for V is [Ar]4s23d3 . However, when electrons are removed – I know it’s weird – the s-electrons come off first. So V2+ would be [Ar]3d3 .

How are the 15 electrons arranged in a phosphorus atom?
A neutral phosphorus atom has 15 electrons. Two electrons can go into the 1s subshell, 2 can go into the 2s subshell, and 6 can go into the 2p subshell. That leaves 5 electrons. Of those 5 electrons, 2 can go into the 3s subshell, and the remaining 3 electrons can go into the 3p subshell.
What is phosphorus P 15 electron configuration?
Answer:The electronic configuration of phosphorus is 1s^2 2s^2 2p^6 3s^2 3p^3.
What element has the electron configuration 2 8 4?
The given electronic configuration 2, 8, 4. Hence there are two electrons in the K shell, eight electrons in the L shell and four electrons in the M shell. Thus the total number of electrons is 14. – Since the atomic number is fourteen we can assume that the given element is silicon.
What does the electron configuration 2 8 7 mean?
Answer: (a) The number of electrons present in an atom is. ⇒ 2+8+7 = 17. Therefore, the atomic number of this element is 17 and the element is chlorine.
Where would you locate the element with electronic configuration 2 8 8 in the Group B Group 8 C Group 2 D 10?
In the modern periodic table, noble gas elements are present in the group 18. Hence, you would locate the element with electronic configuration 2, 8 in the Modern Periodic Table in the group 18. Hence, the option (C) is the correct option.
What will be the atomic number of an element having electronic configuration as 2 8 1?
– As we know that the element that has an electronic configuration (2,8,8,1), hence there are two electrons in K shell, 8 electrons in L shell, 8 electrons in M shell and 1 electron in N shell. Thus, the total number of electrons is 19. We can see that the given element is potassium.

How do you calculate configuration?
To calculate an electron configuration, divide the periodic table into sections to represent the atomic orbitals, the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent the d-block, 13 to 18 are the p-block and the two rows at the bottom are the f-block.
What comes after 5p in electron configuration?
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 is an electron configuration in chemistry?
electronic configuration, also called electronic structure, the arrangement of electrons in energy levels around an atomic nucleus. … In terms of a more refined, quantum-mechanical model, the K–Q shells are subdivided into a set of orbitals (see orbital), each of which can be occupied by no more than a pair of electrons.
