Scandium forms one ion, Sc3+, with an electron configuration of 1s2 2s2 2p6 3s2 3p6.

How many electrons does Sc3+ have?

-The Sc3+ ion contains 21 protons and 18 electrons.

What is the electron configuration of Sc2+?

Sc2+ is 1s2, 2s2, 2p6, 3s2, 3p6, 3d1, 4s.

Does Sc3+ have 8 valence electrons?

That is, scandium is a cation element. The electron configuration of scandium ion(Sc3+) is 1s2 2s2 2p6 3s2 3p6. In this case, the valency of the scandium ion is +3. Since the last shell of a scandium ion has eight electrons, the valence electrons of scandium ion(Sc3+) are eight.

Which of the following is the correct electron configuration for a Sc3+ ion of the element scandium in the ground state?

Scandium has an atomic no. of 21. Therefore electronic configuration of scandium(Sc) is: 1s2 2s2 2p6 3s2 3p6 3d1 4s2.

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.

How do you write electronic configuration for scandium?

The electronic configuration of scandium is Sc: 1s2 2s2 2p6 3s2 3p6 4s2 3d1 .

What is the electronic configuration of scandium Z 21?

1s22s22p63s23p64s13d2.

What is the electronic configuration of Cu Z 29?

Element Cu has an atomic number 29. The electronic configuration should be: 1s2 2s2 2p6 3s2 3p6 4s2 3d9. However, the actual electronic configuration is 1s2 2s2 2p6 3s2 3p6 4s1 3d10 or [Ar] 3d104s1.

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

In the question 1s 2s 2p 3s 3p represents electron orbital energy levels. These orbital energy levels depend on 2 quantum numbers-Principal quantum number (n) and Azimuthal quantum number(l) . Principal quantum number describe the electronic shell of an atom.

How do you find the 11th electron configuration?

The electron configuration of an atom is written with the help of subshell labels. These labels contain the shell number (given by the principal quantum number), the subshell name (given by the azimuthal quantum number) and the total number of electrons in the subshell in superscript.

Which element has the electron configuration 2 8 7?

⇒ 2+8+7 = 17. Therefore, the atomic number of this element is 17 and the element is chlorine. It would be chemically similar to F(9) with configuration as 2, 7.
