Why sodium is more electropositive than chlorine?​

Electronegativity is high because the halogen has a large, unshielded nuclear charge. Sodium is a metal and metals tend to be low in electronegativity

Explanation: Halogen has a large, unshielded nuclear charge which is why the electronegativity is high. Sodium is metal so it tends to be low in electronegativity.

Explanation:

This electropositivity is high because the halogen has a large, unshielded nuclear charge. Sodium is a metal and metals tend to be low in electronegativity (they like to give away their electrons). Chlorine, similar to oxygen, likes to take and keep electrons.

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it
