Which is the most active nonmetal out of argon chlorine potassium or selenium?
chlorine is more reactive than selenium. Chlorine needs one electron to form octet whereas selenium needs two.
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).
What type of items contain selenium?
Plant foods are the major sources of selenium. Brazil nuts are the best natural source (100 grams of nuts provide about 1917 µg of selenium and 3,485% of recommended daily intake). NOTE: You should eat no more than one Brazil nut per day because of their very high selenium content, which can cause toxicity if you eat too much. Other good sources include sunflower seeds, macaroni, crimini mushrooms, and whole grains. The content of selenium in food depends on the selenium content of the soil where plants are grown. For example, soils in the high plains of northern Nebraska and the Dakotas have very high levels of selenium, while soils in some parts of China and Russia have very low amounts of selenium. Likewise, the selenium content of foods can vary. For example, the U.S. Department of Agriculture Food Composition Database lists the selenium content of Brazil nuts as 544 mcg of selenium per ounce, but values from other analyses vary widely.
What is the name formula and uses for one compound that selenium contain?
Selenium dioxide (SeO2) is the most widely used selenium compound in industry. It is used as an oxidising agent in drug and other chemical manufacture, a catalyst in organic syntheses, and an anti-oxidant in lubricating oils.
How many atoms does it to take to have a selenium and oxygen bond?
One atom of Se and one atom of O.
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.
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.
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 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.
Which one is more malleabe iron or sodium?
Sodium is more malleable than iron. But sodium may catch fire may exposed to air / moisture.
Which is the most active nonmetal out of argon chlorine potassium or selenium?
chlorine is more reactive than selenium. Chlorine needs one electron to form octet whereas selenium needs two.
What do sodium ions have more of?
A sodium ion has one more proton than electrons, as the outermost electron has been lost.
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).
Does chlorine and sodium make a compound?
Yes. One Sodium atom and one Chlorine atom make a compound called Sodium Chloride, more commonly known as salt.
Which salt has the most sodium cloride?
The compound for salt is sodium chloride. One type does not "contain" more.
What has one more electron than sodium?
Think it magnesium
Will sodium lose its one valence electron?
Yes, to any more electronegative atom a sodium atom encounters.
