How is the orbital configuration of neutral atoms related to the atoms chemical properties

timama [110]

Answer:

Explanation:

Chemical properties of atoms relies solely on the number of electrons they contain, more particularly, the valence or outermost electrons in the orbit round the nucleus of an atom.

A neutral atom is one that has not gained or lost electron or even shared electrons with any other atom.

On close examination of how electrons are distributed in the orbits of an atom, we can know if an atom will gain or lose electrons in a reaction. This is very important in determining the chemical properties of an atom.

For the formation of ammonia, NH3, the enthalpy of reaction is shown:

Nataly [62]

<u>Answer:</u> The amount of energy required to convert ammonia back to hydrogen and nitrogen is 45.9 kJ

<u>Explanation:</u>

Endothermic reactions are defined as the reactions in which energy is absorbed in the reaction. The enthalpy change of the reaction is positive.

Exothermic reactions are defined as the reactions in which energy is released in the reaction. The enthalpy change of the reaction is negative.

For the given chemical equation:

$3H_2(g)+N_2(g)\rightarrow 2NH_3(g);\Delta H=-45.9kJ$

In the above reaction, the enthalpy change is negative. So, the reaction is exothermic in nature.

For the reverse reaction, the magnitude of the enthalpy change remains the same but sign for it changes.

Hence, the amount of energy required to convert ammonia back to hydrogen and nitrogen is 45.9 kJ
