Since they can still be unstable...nuetral atoms have the same amount of protons to electrons but to be stable they need to fill up there outer shell by gaining or losing electrons
Answer:
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have

The organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.
<h3>What are organs?</h3>
Organs are a collection of tissues that are closely related and which perform a related function.
The role and function of the organs of the digestive system are as follows:
- Pancreas - produces pancreatic juice which contain digestive enzymes
- Liver - produces bile for the emulsification of fat
- Stomach - serves as a temporary store of food and produces digestive juices
- Small intestine - functions in food digestion
- Large Intestine - helps to remove undigested food from the body
Therefore, the organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.

They speed up the breakdown of food in the stomach.
The element which would have the lowest electronegativity is: an element with a small number of valence electrons and a large atomic radius.
Atomic radii can be defined as a measure of the size (distance) of the atom of a chemical element such as hydrogen, oxygen, carbon, nitrogen etc, typically from the nucleus to the valence electrons. The atomic radius of a chemical element decreases across the periodic table, typically from alkali metals (group one elements such as hydrogen, lithium and sodium) to noble gases (group eight elements such as argon, helium and neon). Also, the atomic radius of a chemical element increases down each group of the periodic table, typically from top to bottom (column).
Generally, atoms with relatively large atomic radii tend to have a low electronegativity, ionization energy and a low electron affinity.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Thus, number of valence electrons is typically used to determine the chemical properties of elements such as electronegativity.
Electronegativity can be defined as the ability or tendency of the atom of an chemical element to attract any shared pair of electrons.
In conclusion, a chemical element that has small number of valence electrons and a large atomic radius would have the lowest electronegativity.
