Helium
including "unknown elements" there are 59 elements in half of the periodic table, not including them there is 55.5 Added: 92 natural elements/2 = 46 natural elements make up 1/2 periodic table.
About 2/3 of the Periodic Table of Elements is made up of Metals.
Group 2 elements such as magnesium, calcium, barium, strontium (and also many elements from transition metals)
The second element on the periodic table is helium with atomic number 2. Pi is a mathematical constant used in geometry to represent the ratio of a circle's circumference to its diameter. It is not associated with elements on the periodic table.
there are five element in group 16 of the periodic table
Group 4 elements on the periodic table contain no period 2 elements whatsoever.

Periodic table of elements provides us a lot of information about element's intrinsic properties. We can get the atomic weight of an element by looking at the periodic table. Trends about the electronegativity and atomic size can also be computed.

Yes, magnesium is not considered a transition element. It belongs to Group 2 of the periodic table, known as the alkaline earth metals. Transition elements are typically located in the d-block of the periodic table.
H2O isn't a single element, which is what the periodic table Most things are made of compounds of these elements. . It is comprised of 2 hydrogen atoms (H, on the periodic table) and oxygen (O, on the periodic table).
Neon is in row 2 of the periodic table of elements.
