Calcium is more reactive than sulfur. As an alkaline earth metal, calcium readily reacts with water and acids, while sulfur, a non-metal, is less reactive and typically forms compounds with metals and other non-metals under specific conditions. The reactivity of elements generally increases as you move down the Periodic Table for metals, making calcium more reactive than sulfur.
What else can I help you with?
Is calcium more reactive than strontium?
No, strontium is more reactive than calcium. This is because strontium is located below calcium in the periodic table and thus has a larger atomic size, making it easier for strontium to lose its outermost electron and react with other elements.
Are magnesium and calcium more reactive with oxygen in the air than is aluminum?
Yes, both magnesium and calcium are more reactive with oxygen in the air than aluminum. Magnesium and calcium readily form oxides when exposed to oxygen, while aluminum forms a protective oxide layer that prevents further reaction.
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.
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.
Element M reacts with chlorine to form a compound with the formula MCl2 It is more reactive than magnesium and smaller than barium This element is?
Element M is calcium. It reacts with chlorine to form calcium chloride (CaCl2). Calcium is more reactive than magnesium and smaller than barium on the periodic table.
Is sulfur more reactive than sulfur?
No. Sulfur is more reactive than iron.
Is iron more reactive than sulfur?
Iron is more reactive than sulfur. Iron reacts with water and oxygen to form iron oxide, while sulfur reacts slowly with oxygen to form sulfur dioxide. Iron also reacts with acids to form salts, while sulfur reacts with acids to form hydrogen sulfide gas.
Is selenium or sulfur more reactive?
sulfur is more reactive than selenium
Which is more reactive sulfur or water?
I think sulfur
Is calcium sulfide more or less reactive to aluminum?
Chemistry of calcium Calcium is generally more reactive than magnesium
What is more reactive calcium or more reactive?
Calcium is more reactive but not as Potassium or Sodium because according to the displacement series Calcium comes as third and the last under the reactive elements of the displacement series.
Calcium or bromine which is more reactive?
I believe its Calcium, because it is in group 2, and Bromine is not in group one or two, making Calcium more reactive.
Is sulfur more reactive than sodium?
no... Reactivity Table: Lithium, Potassium, Sodium, Calcium, Magnesium, Aluminum, Zinc, Cadmium, Iron, Nickel, Tin, Lead, Arsenic, Antimony, Copper, Mercury, Silver Platinum, and Gold.
Which is more reactive Phosphorus or sulfur?
Phosphorus is more reactive than sulfur due to its higher electronegativity and smaller atomic size, which allows it to readily form bonds with other elements. Phosphorus reacts vigorously with oxygen and water, whereas sulfur is less reactive and requires more energy to form compounds.
Is oxygen more reactive than sulfur?
Oxygen is generally more reactive than sulfur. Oxygen is highly electronegative and readily forms bonds with other elements, while sulfur is less reactive and tends to form fewer bonds.
Is fluorine more reactive then sulfur?
Yes. Fluorine is extremely reactive, it has a weak F-F bond and readiliy forms the F- ion
Why a sample of sulfur is more dense than a sample of calcium?
Sulfur is more dense than calcium because sulfur has a higher atomic weight and atomic mass compared to calcium. This means that for the same volume of each element, sulfur will have more mass, hence making it more dense.
