WebMar 27, 2024 · The atomic number of an element is equal to the number of protons and electrons in that element. Therefore, a calcium atom has twenty protons and twenty electrons. The number of neutrons in an atom can be determined by the difference between the atomic mass and the number of protons. WebWith arrows, illustrate the transfer of electrons to form calcium chloride from Ca atoms and Cl atoms. Solution. A Ca atom has two valence electrons, while a Cl atom has seven electrons. A Cl atom needs only one more to complete its octet, while Ca atoms have two electrons to lose. Thus we need two Cl atoms to accept the two electrons from one ...

WebTwo Explanation: Valence electron Electron present in the valence shell of an atom is called valence electron. Valence shell The valence shell is the outermost shell of an atom in its uncombined state, which contains the electrons most likely to account for the nature of any reactions involving the atom and of the bonding interactions it has with other atoms.
