Aluminum(26.982) because boron(10.81) is a metalloid.
Boron
Fluorine, at the top of the periodic table column that includes bromine.
H on periodic table is for Hydrogen.It is the first and lightest element on periodic table.It combines with oxygen to form water.
At the top of the periodic table (starting left to right, so hydrogen being the lightest)
The periodic table is arranged by atomic mass. Hydrogen is the lightest element. Its atomic mass is one.
Dmitri Mendeleev arranged the elements in periodic table according to increasing weight. He found their properties to be periodic when arranged in this pattern.
The metalloid with the largest atomic weight and the highest density is Polonium.
No, hydrogen is ?the lightest element in the periodic table.
Hydrogen is the lightest of all elements. According to the Periodic Table, its atomic weight is 1.00794 u, even lighter than helium.
This number you see next to the name on the periodic table is called the atomic number. It is ordered from lightest to heaviest, judging of the weight of an element's specific atom.
Metal is located throughout the periodic table. The periodic table is based on atomic weight. Metals range from some of the lightest to the heaviest of elements.
Helium with an atomic number of 2,is the lightest gas on the periodic table :)
Helium with an atomic number of 2,is the lightest gas on the Periodic Table :)
Chlorine is a non-metal. It is placed in group-17 of the periodic table.
Hydrogen.
Hydrogen is the lightest of all elements. According to the Periodic Table, its atomic weight is 1.00794 u, even lighter than helium.
Towards the top left. Atomic weight increases to the right and down.
Iridium's position on the periodic table indicates that it is a metal.
