The atomic number of zinc is 30, which means that all zinc atoms have 30 protons in their nuclei. A neutral atom has equal numbers of protons and electrons, so a neutral atom of zinc would have 30 electrons.

So we use Ar electron configuration and add 10 more electrons. Since Ni is a petiod 4 transition metal, it will have 3d valence electrons. So, the abbreviated configuration for Ni is [Ar] 4s2 3d8.

The noble gas electron configuration is a type of shortcut to writing out the full electron configuration of an element. The noble gas shorthand is used to summarize the electron configuration of an element while providing the most relevant information about the valence electrons of that element.

Answer: Pb has an electronic configuration of [Xe]6s2 4f14 5d10 6p2. Pb2+ would then have an electronic configuration of [Xe]6s2 4f14 5d10 since Pb2+ means that it lost two of its electrons.

The electron configuration of a Ca2+ ion is: 1s2 2s2 2p6 3s2 3p6, which is isoelectronic with the noble gas argon.

The Noble gas shortcut electron configuration is a way of summarizing the information about the electrons of an atom which shows only the electrons most relevant for understanding the chemistry of the element.

A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of [Ne] for the 1s22s22p6 part of the configuration. Sodium's noble gas configuration becomes [Ne]3s1.

Now, just remove all of the symbols that you added up and put in the noble gas' symbol in brackets. So, for an antimony atom, the noble gas configuration would be [Kr] 5s2 4d10 5p3.

The electronic configuration of Cu+ is [Ar]3d10. It has ten d electrons. Out these, one half, i.e, 5 will have the spin quantum number (−21) and the remaining half will have the spin quantum number (+21). How satisfied are you with the answer?

Vanadium atoms have 23 electrons and the shell structure is 2.8. 11.2. The ground state electron configuration of ground state gaseous neutral vanadium is [Ar]. 3d3.

The noble gases are the only non-transition-metal elements that have eight valence electrons in their neutral, ground state configuration, but atoms of other elements can produce a full octet -- an outer shell with eight electrons -- by gaining or losing electrons.

So zinc has 2 valence electrons that it wishes to transfer. Neutral zinc atom has a total of 30 electronssurrounding its nucleus. To see how many of these electrons arevalence electrons, write the electron configuration of a neutral zincatom.

The atomic number of element zinc (Zn) is 30. The above electron configuration of Zn indicates that the 3d sublevel has 10 electrons. Therefore, the numbers of electrons in the 3d sublevel of Zn are 10.
