What is selenium's malleability?
Selenium is a brittle metalloid, not malleable like metals such as copper or gold. It can easily break, crumble, or be powdered under pressure instead of flattening or bending.
What effects do too much selenium have on your body?
Consuming too much selenium can lead to selenosis, causing symptoms such as hair loss, brittle nails, nausea, and diarrhea. In severe cases, excessive selenium intake can result in organ damage and neurological issues. It is important to stay within the recommended daily intake to avoid these negative effects.
Why is selenium a non metal?
Selenium is a nonmetal because it lacks the physical and chemical properties of metals. It tends to gain electrons in reactions rather than losing them like metals, and it is brittle in solid form rather than malleable and ductile like metals. Additionally, selenium is a poor conductor of heat and electricity, unlike metals.
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.
Is selenium hard or soft?
If you mean the elements in their normal forms, F and Cl are gases, Br is a liquid, I is a solid. If you mean their ligand hard/soft qualities as halide ions:- the lighter ones are hard, Br- and I- soft
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.
Which element is likely to be the most brittle out of selenium cobalt platinum or zinc?
Selenium is the most brittle of the elements listed: The others are all full metals, but selenium is only a semi-metal or a metalloid, and ductility, the negative of brittleness, is a property primarily of metals.

Is selenium a nonmetal?
Yes. selenium is a non metal
Who made Selenium?
Jons Jacob was the man to discover Selenium.
What are the chemical and physical properties of selenium?
Selenium is a nonmetal element with the atomic number 34. It is a brittle solid at room temperature with a metallic luster. It exhibits both photovoltaic and photoconductive properties, making it useful in solar cells and photocopying. Selenium is a semiconductor that can conduct electricity under certain conditions. Its chemical properties include forming compounds with both metallic and nonmetallic elements, and it is essential for various biological functions in trace amounts.
What is selenium chemical symbol?
Se is the symbol for Selenium.
