What type of bond would a calcium atom with the number 20 and a oxygen atom with number 8 form?
They would form an ionic bond. Calcium is a metal and oxygen is a non-metal, and the ionic bond is the most common way these two types of elements get together. Calcium has 2 valence electrons, which it will lose to oxygen, which has 6 and therefore needs 2. Calcium and oxygen will combine in a 1:1 ratio to form calcium oxide with the formula CaO.
What else can I help you with?
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 is the total number of atoms in CaCO3?
five One calcium atom, one carbon atom, and three oxygen atoms.
Does calcium carbonate contains five atoms in its formula?
Yes, the formula is CaCO3. There are three oxygen atoms, 1 calcium atom and one carbon atom.
How many neutrons are in a neutral atom of calcium with a mass number of 41?
A neutral atom of calcium with a mass number of 41 would have 20 protons since calcium has an atomic number of 20. To find the number of neutrons, you subtract the atomic number from the mass number, so there would be 21 neutrons in this atom.
Which elements are in CoCO3?
The compound CaCO3 contains the following elements;Calcium (Ca)Carbon (C)Oxygen (O)1 Calcium Atom, 1 Carbon Atom, 3 Oxygen Atoms
What are the elements and number of atoms in the compound CaCO3?
Calcium carbonate, CaCO3, has one calcium atom, one carbon atom, and three oxygen atoms, which adds up to five atoms.
The ions that are formed when calcium atom and oxygen atom react?
Calcium cation is Ca2+ and oxygen anion is O2-.
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 is the expected formula between calcium and oxygen?
The expected formula between calcium and oxygen is CaO, which is calcium oxide. This compound is formed by the combination of one calcium atom with one oxygen atom.
What is the ionic formula for calcium and oxygen?
The ionic formula for calcium and oxygen is CaO. Calcium has a +2 charge while oxygen has a -2 charge. To balance the charges, one calcium atom combines with one oxygen atom to form calcium oxide.
What is the total number of atoms in CaCO3?
five One calcium atom, one carbon atom, and three oxygen atoms.
What elements make up a Calcium oxide atom?
A calcium oxide atom is composed of one calcium (Ca) atom and one oxygen (O) atom. These two atoms combine through ionic bonding to form the compound calcium oxide (CaO).
What is the atomic number of calcium and what does that number tell you about an atom of calcium?
The atomic number of calcium is 20. The atomic number tells you the number of protons in the nucleus of a calcium atom, which also corresponds to the number of electrons in a neutral calcium atom.
How much oxygen is in calcium carbonate?
There is no oxygen in calcium carbonate. Calcium carbonate is composed of calcium, carbon, and oxygen atoms. The chemical formula for calcium carbonate is CaCO3, indicating that each molecule contains one calcium atom, one carbon atom, and three oxygen atoms.
Does calcium carbonate contains five atoms in its formula?
Yes, the formula is CaCO3. There are three oxygen atoms, 1 calcium atom and one carbon atom.
Calcium's atomic number is 20. What does that that tell us about a calcium atom?
this is poopie head
What is the constituent element of calcium carbonate?
The constituent elements of calcium carbonate are calcium, carbon, and oxygen.
