How many moles of selenium in selenium tetra-fluoride?
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.
Does 24Na has one more proton than 23Na?
Yes, sodium-24 (24Na) has one more proton than sodium-23 (23Na). Sodium-24 has 11 protons, while sodium-23 has 10 protons.
How many bonds can selenium form with hydrogen?
Each hydrogen can form one bond with selenium. Each selenium atom can form two bonds, one with each hydrogen (2 hydrogen atoms total).
Which is the most active nonmetal out of argon chlorine potassium or selenium?
Chlorine is the most active nonmetal out of argon, chlorine, potassium, and selenium. It belongs to the halogen group, which is known for its high reactivity. Chlorine readily reacts with other elements to form compounds.
What do sodium silicon sulfur and selenium have in common?
They are all chemical elements in Group 16 of the periodic table. The atomic number of each element (number of protons in an atom) is: oxygen 8 sulfur 16 selenium 34 tellurium 52
Which one of the following is brittle sodium aluminium selenium or magnesium?
Selenium is the only brittle element among the four listed: The others are all metals, with the usual ductility of metals, but selenium is only a metalloid at most.
What is the chemical formula for the compound formed between sodium and selenium?
The chemical formula for the compound formed between sodium and selenium is Na2Se. Sodium has a +1 charge, and selenium has a -2 charge, so two sodium atoms combine with one selenium atom to form a stable compound.
Hardness of sodium chloride?
Sodium Chloride IS hard, just brittle, that's why it breaks apart in your hands. The hardness of sodium chloride is 2,5 on the Mohs scale.
How many moles of selenium in selenium tetra-fluoride?
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.
What weighs more one mole of oxygen or one mole of sodium?
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.
What has one more electron than sodium?
Potassium has one more electron than sodium, as it has 19 electrons compared to sodium's 11 electrons.
What element has one more proton than sodium?
The element with one more proton than sodium is magnesium. Sodium has 11 protons, while magnesium has 12 protons.
Does 24Na has one more proton than 23Na?
Yes, sodium-24 (24Na) has one more proton than sodium-23 (23Na). Sodium-24 has 11 protons, while sodium-23 has 10 protons.
What is the ductility of sulfur?
I don't know what is if or if it has one, this site is worthless, get off of it. It won't help you.
What is the binary compound SeO?
The binary compound SeO is selenium dioxide. It is composed of one selenium atom and two oxygen atoms. Its chemical formula is SeO2.
What do sodium ions have more of?
A sodium ion has one more proton than electrons, as the outermost electron has been lost.
What is the formula for fluorine with selenium?
The formula for the compound made of fluorine and selenium would be SeF4. This is because fluorine typically forms one bond, while selenium typically forms four bonds, resulting in a compound with four fluorine atoms bonded to one selenium atom.
