What happens to the outer shell of a calcium atom when it reacts with an oxygen atom?
When a calcium atom reacts with an oxygen atom, the calcium atom loses two electrons from its outer shell and the oxygen atom gains those electrons. This forms a calcium ion with a 2+ charge and an oxygen ion with a 2- charge. These ions then bond together to form calcium oxide.
Would the compound calcium oxide have covalent or ionic bonds?
Ca2O should be an ionic bond since it is a metal(Ca) bonded to a non metal(0). Since it is oxIDE it is elemental oxygen.
An oxide ion is oxidized to an oxygen atom by what?
An oxygen atom can only be oxidized by some element with an equal or higher electronegativity. So, oxygen can be oxidized by fluorine (e.g., OF2) or by another oxygen atom (e.g., O2).
When calcium metal reacts with oxygen gas in the air to form calcium oxide suppose you react 6.55 mol calcium with 4.00 mol oxygen now determine the number of moles of calcium oxide produced?
Calcium contains only one atom per molecule, while oxygen contains two. The usual reaction product from a reaction between calcium and oxygen has the formula CaO and therefore contains one atom of each element per molecule. 4 moles of oxygen provides 8 moles of oxygen atoms, so that under the conditions given, calcium is the limiting reactant, and 6.55 moles of calcium oxide will be formed.
What happens in terms of electrons when lithium reacts with oxygen?
Oxygen is more electronegative than lithium, a metal. Oxygen has a tendency to gain two electrons so it will bond with two lithium atoms which have a tendency to donate one valence electron for bonding. Li2O
What happens to the outer shell of a calcium atom when it reacts with an oxygen atom?
When a calcium atom reacts with an oxygen atom, the calcium atom loses two electrons from its outer shell and the oxygen atom gains those electrons. This forms a calcium ion with a 2+ charge and an oxygen ion with a 2- charge. These ions then bond together to form calcium oxide.
What happens to beryllium electrons with oxygen?
When beryllium reacts with oxygen, it forms beryllium oxide. Beryllium loses its two valence electrons to oxygen, which gains these electrons to form an ionic bond in beryllium oxide.
Name the compound that is formed when calcium and oxygen react together?
Calcium oxide is formed when calcium reacts with oxygen.
What element reacts with fluorine and loses two electrons?
Beryllium, Magnesium, Calcium, Strontium, Barium and Radium
What is the gas that reacts with calcium and magnesium when they burn?
Hydrogen gas is released when calcium and water react.
What compound is produced when calcium reacts with oxygen?
Calcium oxide (CaO) is produced when calcium reacts with oxygen. This compound is also known as quicklime and is commonly used in various industrial processes and applications.
What compound does calcium sulfur and oxygen make?
Calcium sulfite is formed when calcium reacts with sulfur and oxygen. The chemical formula for calcium sulfite is CaSO3.
Calcium reacts with fluorine to form what?
Calcium reacts with fluorine to form calcium fluoride (CaF2).
What happens when Calcium reacts with water?

What happens when calcium carbonate reacts with acid?
It Bubbles
What happens when oxygen is put in to lime water?
When oxygen is added to lime water (calcium hydroxide solution), it reacts with the calcium hydroxide to form calcium carbonate. This reaction causes the lime water to turn milky due to the formation of calcium carbonate, which is insoluble and settles out of the solution as a solid.
Calcium plus carbon plus oxygen plus oxygen plus oxygen equals?
Calcium plus carbon plus oxygen plus oxygen plus oxygen equals calcium carbonate (CaCO3), which is a chemical compound that forms when calcium reacts with carbon and oxygen.
