Answer:

Determine the value of the oxidation numbers of atoms or ions on the reactant side and the product side.

Explanation:

A redox reaction involves some ions, and atoms losing electrons and other gaining them in the same reaction. When oxidation occurs, there is loss of electrons by an element thus its oxidation number increases; becomes more positive. When reduction occurs an element gains electrons and the oxidation  number becomes more negative; reduces.

If an element (s) behaves in this manner in the whole reaction, then be sure to deduce that a redox reaction has occurred.

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.

Round the following answer correctly. 5.40m x 3.21m x 1.871m = 32.431914 m^3
Klio2033 [76]
The answer is 32.43 because when you round the number next to the hunthers place (witch in this problem would be the 1) has to be 5 or hight to raise the number to the left of it and if it is lower you just take the two number and that is your answer.
