What is the protons and electrons of element calcium?
Calcium has an atomic number of 20. Thus calcium's number of protons is 20. To balance out these protons' positive charges, calcium also is found with 20 negatively charged electrons.
What is the chemical balance formula for Ca(oh)2?
The chemical formula for calcium hydroxide is Ca(OH)2. It consists of one calcium ion (Ca2+) and two hydroxide ions (OH-). The balance of charges is achieved by the two negative charges from the hydroxide ions balancing the positive charge from the calcium ion.
How the formula of compound is derived using the formula of calcium chloride explain?
The formula for calcium chloride is derived from the charges of its constituent ions. Calcium (Ca) has a +2 charge as an alkaline earth metal, while chloride (Cl) has a -1 charge as a halogen. To balance the charges, one calcium ion combines with two chloride ions, resulting in the formula CaCl₂. This indicates that for every calcium ion, there are two chloride ions to achieve electrical neutrality in the compound.
Does the fact that two elements combine in a one-to-one atomic ratio mean that the charges on their ions are both 1?
No. Calcium Sulphide is one counter example.No. Calcium Sulphide is one counter example.No. Calcium Sulphide is one counter example.No. Calcium Sulphide is one counter example.
What are the charges when calcium and oxide ions form?
When calcium and oxide ions form, calcium (Ca) typically loses two electrons to achieve a stable electronic configuration, resulting in a charge of +2 (Ca²⁺). Oxide (O) ions, on the other hand, gain two electrons to fill their outer shell, resulting in a charge of -2 (O²⁻). Therefore, the charges on the ions are Ca²⁺ and O²⁻, which combine to form calcium oxide (CaO) in a 1:1 ratio, balancing the overall charge to neutral.
How calcium and phosphate can make a compound with electroneutrality?
Calcium (Ca) has a 2+ charge and phosphate (PO4) has a 3- charge. To form a compound with electroneutrality, two phosphate ions will combine with three calcium ions. This results in the formation of calcium phosphate (Ca3(PO4)2), which is electrically neutral due to the balanced charges of the ions.
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 chemical formula for chalk calcium and carbonate?
calcium cation = Ca2+ carbonate ion = CO32- the charges should cancel and you have the correct formula
Is calcium hydroxide a polar substance?
Calcium hydroxide is an ionic compound, therefore it has no polarity.

What is the molecular formula for calcium chloride?
These are the ions and their charges: Ca+2 Cl-1The charges have to add up to zero, so one +2 calcium ion cancels out two -1 chlorine ions: Ca+2 Cl-1 Cl-1Simplify: CaCl2
What type of bond calcium and oxygen?
Calcium and oxygen can form an ionic bond to create calcium oxide (CaO). In this compound, calcium will donate two electrons to oxygen, resulting in the formation of a positive (Ca2+) and a negative (O2-) ion which are attracted to each other due to their opposite charges.
Correct formula for a compound formed between calcium and phosphate?
CaF2 is calcium fluoride...ANS2:Ca3(PO4)2

What is the formula of the ionic compound of calcium iodide?
The formula of calcium iodide is CaI2. This is because calcium is a group 2 element with a 2+ charge, while iodide is a group 17 element with a 1- charge. Therefore, to balance the charges, two iodide ions are needed for each calcium ion.
