The second lightest element on the Periodic Table is Helium (He). The easiest way to tell this is by the numbers on the periodic table, all elements are in atomic weight order (super-light gases to super-heavy elements).
Presumably you are talking about molecular mass, in which Hydrogen would be the lightest element.
In gaseous form, Hydrogen is also lighter than other elements (at the same temperature/pressure), and thus it was commonly used in early blimps prior to the traumatic explosion of the Hindenburg.
The lightest is Hydrogen, then comes Helium, and so on. If you have a periodic table with you, it just goes in the order of the numbers they are labeled.
Hope that helped. If it didn't, just add on to the answer and say what you need to know.
Helium its the lightest element with the atomic #:2
Oxygen (mass 15.999).
Hydrogen, with a molar mass of 1.00784 u
Lithium.
Hydrogen.

Periodic table show that elements have properties which are periodic in nature. These properties can be grouped together.
Iron. That is why iron's symbol on the Periodic Table of Elements is 'Fe'.
It is named after Dmitri Mendeleev, the scientist who was responsible for devising the periodic table of elements.
Yttrium is a science word that begins with the letter 'y'. Yttrium is a name of element and you can find this on the periodic table. The use of this element has increased in making ultra pure compounds.
Alkali metals
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.
The element abbreviated with As on the periodic table is Arsenic
Hydrogen (H) is the first element in the periodic table.
Symbols represent name of the element. They signify the position of element in periodic table.
Hydrogen is the lightest element on the periodic table. Henry Cavendish collected Hydrogen by placing Zinc in an acid and originally called it inflammable air. However, Paracelsus of Switzerland had noticed 250 years before that Iron placed in acid gave off a gas and that gas would burn: but did not study it further.
The element that has the element name of France is francium.
Carbon's name is C on periodic table. It belongs to group no. 14.
Everything on The Periodic Table is an element, hence the the name PERIODIC TABLE OF ELEMENTS - - - - - Well...the paper the table is printed on and the ink used to print it with are not elements, but everything else is.
Yes, each element on the periodic table has a unique name and chemical symbol.
Name of the element(basically symbol) is present in periodic table. It also contains its atomic number.
The element with atomic number 55 on the periodic table is cesium.
Element 110 is called Darmstadtium.
