The electrons are what determines the energy level and reaction of the valence shell, hope it helps ❤️✌️
The force that accelerates objects towards Earth is gravity.
Solubility: the ability for a given substance (the solute) to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium
Explanation:
Atomic size is defined as the distance between the nucleus and valence shell of an atom. Valence shell is the outermost shell of an atom.
When we move across a period in a periodic table then there will occur a decrease in atomic size of the atoms. But when we move across a group in a periodic table then there will occur an increase in atomic size of the atom.
Hydrogen is a period 1 element, oxygen is a period 2 element, chlorine is a period 3 element and bromine is a period 4 element.
Therefore, given elements are arranged in order of increasing atomic size as follows.
H < O < Cl < Br
