Lower as KCl has ionic bonding which is less stable than CaCl2s covalent bond which requires less energy.
Answer:
Therefore the Chlorine electron configuration will be 1s22s22p63s23p5. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.
Explanation:
For the answer to the question determine the total charge of the boron if t<span>he nucleus of one boron atom has 5 protons and 4 neutrons. The answer to this question is +5 for the charge of the boron.

<span>After four half-lives 0.1 mole of the radioactive isotope would remain. If the amount of the isotope that remains after each half life is one half of previously existing amount. Half of 1.6 equals 0.8, half of 0.8 equals 0.4, half of 0.4 equals 0.2, and finally half of 0.2 equals 0.1 mole.</span>
