How many atoms are there in one mole of sulfur? - Answers
WebOne mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant. The concept of the mole can be used to convert between mass and number of particles.. Created by Sal Khan. WebJun 4, 2024 · If we look at the electron configuration of sulfur ( 1s22s22p63s23p4 ). Since the third p orbital holds the maximum of 6 electrons and sulfur only have 4 this means that sulfur have 2 unpaired electrons. This is why disulfur have a double bond between two sulfur atoms.
