Is water (H20) a diatomic element?

Question

and do you know if glucose (C6H12O6) is a binary compound or diatomic element? this is so confusing

Answer 1

First, water is not an element. It is a compound composed of two different elements - hydrogen and oxygen. It may be referred to as a BINARY compound since it has two elements.

A DIATOMIC ELEMENT is composed of two atoms of the same element - H2, O2, N2, F2, Cl2, Br2, I2 at the 7 diatomic elements. They are only diatomic in their elemental form. When they combine with other elements they are no longer diatomic.

Glucose is neither a binary compound nor a diatomic element. It is composed of three different elements - carbon, hydrogen, and oxygen. A compound composed of three or more elements is called a TERNARY COMPOUND.

The way to tell the difference between a diatomic element, binary compound, and ternary compound is to count the number of elements present. (You can count the number of capital letters to determine the number of elements.)

1 element with a "2" subscript is a diatomic element.
2 elements is a binary compound.
3 or more elements is a ternary compound.

Answer 2

First: Water is a Compound not an Element.

Water is not 'Diatomic' as this refers to 2 atoms of the same or different elements in its. makeup.

It is probably classed as 'Triatomic' (2 x H and 1 x O)

Glucose has 24 atoms - Definitely not di or tri - atomic.

Binary and Diatomic mean the same thing = 2 atoms in the make-up.
