That really depends on the age of the periodic table you’re referring to. Mendeleev’s original periodic table had only 50 elements. Today, the most modern Periodic table has 118 elements.
Answer:s: It is durable, low cost, water resistant, lesser energy and heavy chemicals requirements in manufacture and are light weight
Explanation:
O
Explanation:
Oxygen is a more reactive non-metal.
There are several parameters to test how reactive an element is. In this case, we are going to use the electronegativity of the two atoms.
- Electronegativity is the relative tendency with which atoms of the element attract valence electrons in a chemical bond.
A high electronegativity value suggests more reactivity and a low value implies low reactivity.
On the Pauling's Eelectronegativity table, Oxygen has a value of 3.5 and Phosphorus has 2.1
It implies that oxygen is a more reactive non-metal compared to phosphorus.
