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.
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.
Which is more metallic oxygen vs selenium?
Selenium is more metallic than oxygen. Oxygen is a non-metal, while selenium is a metalloid that exhibits some properties of metals.
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 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 does selenium and oxygen combined together make?
Selenium dioxide, SeO2
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.
Which is more metallic oxygen vs selenium?
Selenium is more metallic than oxygen. Oxygen is a non-metal, while selenium is a metalloid that exhibits some properties of metals.
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.
Is nitrogen more reactive than oxygen?
No, oxygen is more reactive than nitrogen. Oxygen readily forms compounds with other elements, while nitrogen is relatively inert under most conditions.
Is argon more reactive than oxygen?
No, argon is not more reactive than oxygen. In fact, argon is a noble gas and is very non-reactive, while oxygen is a highly reactive element that readily participates in chemical reactions.
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.
Which is more electronegative O or Se?
Oxygen (O) is more electronegative than Selenium (Se) because oxygen is higher up and to the right in the periodic table, which increases its ability to attract and hold onto electrons in a chemical bond.
What is more reactive than oxygen?
Fluorine is more reactive than oxygen. It is the most reactive non-metal element and readily forms compounds with almost all other elements.
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 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.
Which two elements in the periodic table are more alike oxygen?
sulphur, selenium
