Oxygen, the upper one in group 16
Fluorine
Sulfur is an element that is a yellow non-metallic solid.
Fluorine has the most non metallic qualities.
Chlorine has the most metallic character among fluorine, chlorine, bromine, and iodine since it is the closest to the metalloids in the periodic table and exhibits some metallic properties. Fluorine is the most non-metallic element of the group.
hydrogen, carbon, oxygen. But don't forget silicon.
Sulfur is a non-metallic element. It is in group 16 of the periodic table, also known as the chalcogens. It is not classified as a metal due to its physical and chemical properties.
No, baking soda (sodium bicarbonate) does not contain metallic elements. It is composed of sodium (a metal) and bicarbonate (a non-metallic element).
A sharpened pencil lead is non-metallic. It is typically made of graphite, which is a non-metallic element.
Recent events would suggest Polonium Po as the most lethal non-metllic element. see link.
Hydrogen is considered a non-metallic element because it does not possess the typical properties of metals, such as high electrical conductivity and luster. It is a diatomic gas at room temperature and does not exhibit metallic bonding characteristics.
Group VII and Group 8 ( the noble gases)
No, water is not an element, it is a compound.
