What is the noble gas configuration for the following: fluorine, phosphorus, bromine, manganese, copper? Hi Listen to Jenny Bee as she has the right answers. You count and record from the previous noble gas to get the correct noble gas configuration. As a double check the sum of electron configuration e.g. For Phosphorus-Neon has a value of 10 (as per periodic table) so 10 + 2 + 3 = 15. The atomic number of phosphorus is 15 so this is correct. Check the others and you will find that Jenny is correct.

- The formula of zinc fluoride is ZnF2. Therefore, its molar mass is the sum of the atomic mass of zinc and twice the atomic mass of fluorine: 65.39 + 2(18.999) = 103.39; the la … st digit is depressed because it may not be significant, since the atomic mass of zinc (at least in my reference) has only four significant digits.

How to Write the Electron Configuration for Neon How to Write the Electron Configuration for Neon. Neon is the tenth element with a total of 10 electrons. In writing the electron configuration for neon the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Ne go in the 2s orbital. The remaining six electrons will go in the 2p orbital. Therefore the Ne electron configuration will be 1s22s22p6.

Zinc Brass, which is an alloy of copper and zinc, has been used since at least the 10th century BC in Judea and by the 7th century BC in Ancient Greece. Zinc metal was not produced on a large scale until the 12th century in India and was unknown to Europe until the end of the 16th century.inc methyl (Zn(CH3) 2) is used in a number of organic syntheses. Zinc sulfide (ZnS) is used in luminescent pigments such as on the hands of clocks, X-ray and television screens, and luminous paints. Crystals of ZnS are used in lasers that operate in the mid-infrared part of the spectrum.
