Atoms are electrically neutral because they possess an equal number of electrons and protons. However, when an atom has an unequal number of protons and electron, it has an electrical charge and they create ions. If an ion has more protons than electrons, it is positively charged and is called a cation. Did you mean Ca(H2PO4)2?
