Every type of atom currently know to man. It consists of 118 elements, though the number is always changing.
Groups are the vertical columns present in the periodic table.
All the groups are arranged in such a manner so that it consists of the elements with same no. of valence electrons.
K.
Helium (He) in a noble or inert gas, and it is in Group 18 of the periodic table.
Hydrogen is the first element on periodic table. Its atomic number is 1.
False.
who introduced the first Periodic Table
Mardelev was the scientist who was the first person to discorver or invent the peridoic table!
Most of the symbols on the Periodic Table have symbols for the latin name of the element. AU = Aureum = Gold.
K.
Helium (He) in a noble or inert gas, and it is in Group 18 of the periodic table.
Dmitri Mendeleev
Metals in group 1 on peridoic table
Dmitri Mendeleev was the inventor of the periodic table of elements.
No. Every substance in the Periodic Table is an element - that is, a substance that cannot be broken down into a simpler form. For example, H2O is made of the elements hydrogen and oxygen. Blood, however, is a homogeneous mixture, not an element, and can be broken down into simpler substances, so it does not belong on the Periodic table.
Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
The first element of the Mendeleev's periodic table is hydrogen (H).
Hydrogen is the first element on periodic table. Its atomic number is 1.
The first element in the periodic table of Mendeleev is hydrogen, not carbon.
