This video explores the fascinating reasons behind the physical properties of elements. It answers questions about why ...

If phosphorous has five electrons in its outermost shell, meaning it needs only three more to fill the shell, how can it form FOUR valence bonds when used as a dopant in a silicon crystal? This is one ...

The distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan. As the ...

The number of electrons in the element's outer shell hugely influences reactivity. If the outer electron shell is full then an additional chemical bond cannot be formed because there is no room. Inert ...

Many of us are often told we bear a resemblance to another member of our family — for instance, that we have our mother’s nose or our father’s eyes. Chemical elements on the periodic table also have ...
