An element with atomic number 7 (nitrogen) can make a maximum of 3 covalent bonds, while an element with atomic number 16 (sulfur) can make a maximum of 2 covalent bonds. Therefore, when they combine, they can form a total of 5 covalent bonds between them.
The element with an atomic number of 8 is Oxygen. It has 2 electrons in the first shell and 6 in the second, leaving a valence of 2. Oxygen, therefore, can form covalent bonds with only two Hydrogen atoms. This is also known as water.
The atomic number of the chemical element hydrogen is 1.
Hydrogen chloride is not an element; it is a compound and has no atomic number!
Hydrogen is a gas. atomic number of H is 1.
Hydrogen is a non metal element. Atomic mass of it is 1.0079.
Hydrogen is a non metal element. Atomic number of it is 1.
Hydrogen is the element with the Atomic Number 1.
Hydrogen is a non meta element. Atomic Mass of it is 2.
Hydrogen is a non meta element. Atomic Mass of it is 2.
A gold atom is larger than a hydrogen atom. This is because gold has a larger atomic radius and more electrons, which results in a larger atomic size compared to hydrogen.
