The neutral atom with 44 electrons is ruthenium (Ru).The electron configuration of ruthenium is: [Kr]4d75s1.The number of electrons in shells is: 2, 8, 18, 15, 1.
Some examples of elements is iron(Fe), Hydrogen (H) and Sulfur(S).Elements presents in periodic table like hydrogen , helium , lithium , beryllium , boron ,carbon , nitrogen , oxygen etc called elementsAn element is a substance that can not be broken down into any other chemically distinct substance. Examples would be sulfur, oxygen, nitrogen, gold, and lead.

1 mole Kr = 6.022 x 1023 atoms 1.7 x 1025 Kr atoms x (1 mole Kr)/(6.022 x 1023 Kr atoms) = 28 moles Kr (rounded to two sig figs)
Just multiply the moles of Kr by Avogadro's number. Formal set up.1.29 moles Kr (6.022 X 1023/1 mole Kr)= 7.77 X 1023 atoms of krypton====================
0.377 grams of Kr is equal to 0,0045 moles.
7.98 moles of Kr have 668,708 g.
7.98 moles of Kr have 668,708 g.
3,99 moles of Kr have 334,35 g.
3,99 moles of Kr is equal to 334,354 g.
Natural isotopes of krypton are: Kr-78, Kr-80, Kr-81, Kr-82, Kr-83, Kr-84, Kr-86.
Natural isotopes of krypton are: Kr-78, Kr-80, Kr-81, Kr-82, Kr-83, Kr-84, Kr-86.
Given the balanced equation Kr + 3F2 --> KrF6 In order to find how many moles of F2 are needed to produce 3.0 moles of KrF6, we must convert from moles to moles (mol --> mol conversion). 3.0 mol KrF6 * 3 molecules F2 = 9.0 mol F2 --------- 1 molecule F2
The mass of 1 mole of an element is its atomic weight on the periodic table in grams.1g = 1000mgThe mass of 1 mole of Kr = 83.80g KrConvert mg Kr to g Kr.398mg Kr x (1g/1000mg) = 0.398g KrConvert g Kr to mol Kr.0.398g Kr x (1mol Kr/83.80g Kr) = 4.75x10-3mol Kr
3.99 moles × 83.8 grams/mol = 334.362 grams
