WebJan 30, 2024 · The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds. When discussing the octet rule, we do not consider d or f electrons. WebAtoms tend to have all its valence orbitals occupied by paired electrons. For transition metals, the valence orbitals consist of ns, 3 np and 5 (n-1)d orbitals, leading to its tendency of being surrounded by 18 electrons. This is somewhat analogous to the octet and Lewis structure rules of main group elements in a simplified rationale.
WebCoulomb (C) is the SI unit of charge. Hence it can be used the express the charge possessed by any body, not necessarily a proton or electron. In this case, a proton possesses a charge of +1.602176634×10^−19 C and electron of -1.602176634×10^−19 C (positive and negative respectively) Hope that helped. WebThe number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Therefore, the number of electrons in neutral atom of Calcium is 20. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom.

WebJan 5, 2024 · Atomic number of calcium is 20 and its electronic configuration is 2, 8, 8, 2. So, to acquire stability it loses 2 valence electrons and hence forms ion. Whereas atomic number of oxygen is 8 and its electronic distribution is 2, 6. And, to attain stability its needs to gain two more electrons and hence then it forms ion.
WebMost of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.
