The electron cloud model uses the basic idea of Bohr's model, representing the atom as if it were cut in half. The difference is that Bohr's model showed electrons in "shells" which modeled that they moved only in a distinct orbit around the nucleus. The modern model has layers of electrons, but models the concept that they form a cloud where their exact position is impossible to known (considering is changes). The modern model explains that electrons are not at a fixed distance from the nucleus, but the Bohr model does not represent this understanding, instead, it displays a concept that the electrons are at fixed levels of orbit.

Answer:

According to modern model of atom that is the electron cloud atom, the electrons are found in orbitals. Orbitals are the region where there is probability to find an electron in an atom. According to Bohr's model, electrons revolve around the nucleus in fixed energy shells.

Electron cloud model explains that the position of electron cannot be found exactly. It can be found in a region. The repeating nature of chemical properties of atoms in periodic table can be explained by both the models.

Write the balanced chemical equations for the decomposition of solid calcium hydroxide into solid calcium (ii) oxide (lime) and
Lesechka [4]

Calcium oxide (CaO) or lime in solid form can be prepared from the decomposition of calcium hydroxide {Ca(OH)_{2} in to lime (CaO) and water (H_{2}O at high temperature. The reaction is an endothermic reaction. That is heat is absorbed in this reaction process. One mole of calcium hydroxide decomposed into one mole of calcium oxide and one mole of water. The balanced reaction can be shown as-CaCO_{3} (solid) → CaO (solid) + H_{2}O (liquid). The heat of the reaction is (+) 63.7 kJ/mole of CaO.
