An Element is the substance that has only one kind of atom.
An element :)
An Element.
Hydrogen is the first atom on the periodic table.It has atomic number 1.It is represented by symbol H.
The horizontal lines are called "periods" and show how many "shells" each atom hasThe horizontal rows in the periodic table are called periods. The vertical columns are called groups.
The nucleus of an atom contains protons and neutrons, which are comprised of up and down quarks. The proton contains two up quarks and one down quark, while the neutron contains one up quark and two down quarks.
Atoms are the things that make up the world, so they are found everwhere.
the name of the elements are found on most periodic tables and each element is a separate type of atom the number found by an element hereorhere shows the number of atoms of each element the molecule has
group 1
It is about nitrogen. N atom contains 7 protons.
The periodic table?
hydrogen, carbon, oxygen, anything on the periodic table with only one letter for its symbol
A atom is not on the periodic table, atoms are inside the elements and compounds on the periodic table if this helps :)
elements
Every individual block on the periodic table ... all hundred-and-some of them ... represents an atom, with a structure different from all the other ones.
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
it is the atomic number.
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
5 protons in one atom of boron. look at the periodic table.
No. Atoms on the Periodic Table are listed by element in order of atomic number, which is the number of protons an atom contains. The number of neutrons in the atoms of an element usually varies among several isotopes.
