There is one mole of selenium in one mole of selenium tetrafluoride, as the formula for selenium tetrafluoride is SeF4. Therefore, there is 1 mole of selenium in 1 mole of selenium tetrafluoride.
There are 34 protons in a selenium-76 atom.
Neutral selenium has 6 valence electrons.
45
Selenium typically loses 2 electrons to achieve a stable electron configuration. This results in the formation of a 2+ ion for selenium.
0.5kg per 500grams.
That is approximately 4 cups
Selenium has 34 electrons.
There is one mole of selenium in one mole of selenium tetrafluoride, as the formula for selenium tetrafluoride is SeF4. Therefore, there is 1 mole of selenium in 1 mole of selenium tetrafluoride.
selenium is inside many foods ,soil, and glass
Number of protons in Selenium is 34.
500g is 0.5kg. so .748/.5 is 1.496 lots of 500g
Selenium has 6 valence electrons
There are 34 protons in a selenium-76 atom.
Selenium can form two bonds with hydrogen.
3 atoms per molecule of CS2. 1 mole of a substance = 6.022 x 1023 molecules.So (1 mole) *(3 atoms/molecule) *(6.022 x 1023 molecules/mole) = 1.8066 x 1024 atoms.
20 10kg is 10,000 grams and 20x500 = 10,000.
