Atomic number=protons=neutrons or, A-P-E. So, an element like this doesn't exist because protons and electrons have the same number.
Height and weight are quantitative increase in the size of a certain anatomical structure.
<h3>What is Weight?</h3>
The gravitational force acting on the object, expressed as weight as a vector quantity. Some people refer to weight as a scalar quantity that measures the gravitational force's strength. Others define it as the strength of the force applied to a body by systems that work to counteract the effects of gravity. For example, a spring scale measures weight. As a result, the weight would be zero during free fall.
Terrestrial objects are capable of having no weight in this sense. For example, if we disregard air resistance, the famous apple falling from the tree and hitting the ground near Isaac Newton would have no weight.

It is estimated that the agriculture was invented 10000 to 12000 year ago. At this period of time, the modern humans or the <em>Homo sapiens</em> were spread to America.
