yes, it is a non metal and it is placed on the right side of the Periodic Table, reactivity increases from left to right on the Periodic Table. since selenium is in group 16 out of 18 groups, it is a very reactive element.
hope this helps you!
What else can I help you with?
Is selenium non reactive?
Selenium can be reactive and form compounds with other elements. It reacts with oxygen to form oxides and with water to form various compounds. However, it is less reactive compared to other elements in the same group like sulfur and tellurium.
What is more reactive oxygen or selenium?
Oxygen is more reactive than selenium. Oxygen is a highly reactive element that readily forms compounds with other elements, while selenium is less reactive in comparison. Oxygen's reactivity is evident in its ability to support combustion and oxidation reactions, whereas selenium's reactivity is more limited due to its position in the periodic table.
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.
Why selenium is more reactive than sulfur?
Selenium is more reactive than sulfur because it has a lower ionization energy and higher electronegativity, making it more readily form bonds with other elements. Additionally, its larger atomic size allows for easier electron transfer, enhancing its reactivity compared to sulfur.
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 or sulfur more reactive?
sulfur is more reactive than selenium
Is selenium non reactive?
Selenium can be reactive and form compounds with other elements. It reacts with oxygen to form oxides and with water to form various compounds. However, it is less reactive compared to other elements in the same group like sulfur and tellurium.
What is the nonmetal in period 4 that is more reactive than selenium?
The nonmetal in period 4 that is more reactive than selenium is sulfur. Sulfur is located above selenium in the same group (group 16) on the periodic table, making it more reactive due to its higher electronegativity and tendency to gain electrons in chemical reactions.
What is more reactive oxygen or selenium?
Oxygen is more reactive than selenium. Oxygen is a highly reactive element that readily forms compounds with other elements, while selenium is less reactive in comparison. Oxygen's reactivity is evident in its ability to support combustion and oxidation reactions, whereas selenium's reactivity is more limited due to its position in the periodic table.
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.
Does selenium blow up with chlorine?
It doesn't seem likely. Selenium isn't terribly reactive, and selenium monochloride exists in equilibrium with a different kind of selenium chloride, chlorine gas, and elemental selenium; this indicates that there's not a huge energy difference between the uncombined elements and the compound, as you would expect there to be if they "blew up" when combined.
Which is more reactive Br Se or Cl?
Bromine (Br) is more reactive than chlorine (Cl) and selenium (Se). Bromine has a lower ionization energy and a larger atomic radius compared to chlorine and selenium, making it more willing to participate in chemical reactions.
Why selenium is more reactive than sulfur?
Selenium is more reactive than sulfur because it has a lower ionization energy and higher electronegativity, making it more readily form bonds with other elements. Additionally, its larger atomic size allows for easier electron transfer, enhancing its reactivity compared to sulfur.
Which is a colorless odorless gas with low chemical reactivity based on the periodic table selenium chlorine xenon or carbon?
Xenon as it is a noble gas. Noble gases are inert and do not react with anything. Selenium is a solid Chlorine is a green coloured highly reactive poisonous gas. Carbon is a non-metallic solid.
What is the correct name for SeF6?
This compound is called selenium hexafluoride.
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 a nonmetal?
Yes. selenium is a non metal
