The atomic number tells us the number of electrons and the number of protons., i.e. Atomic Number = Number of electrons = Number of Protons. The Atomic Mass tells the total number of particles in the nucleus, i.e. Atomic Mass = # of protons + number of neutrons. The Group number is the heading at the top of a column in the table. It tells the the outer electron configuration of the atom. This determines many chemical properties of the element.
Argon is in the third period of the modern periodic table.
The element with the largest atomic number on the periodic table is Oganesson, with the atomic number 118.
The vertical columns of a periodic table are called groups or families. They share similar chemical properties because they have the same number of valence electrons.
Elements are organized in the periodic table by their atomic number, which represents the number of protons in the nucleus of an atom. The atomic number determines the unique properties of each element, and elements with similar properties are grouped together in columns called groups.
Oh, dude, radium is like that cool kid hanging out in Group 2 of the periodic table, also known as the alkaline earth metals. It's chilling right below barium and above francium, just doing its thing, being all radioactive and stuff. So yeah, radium is like the rockstar of Group 2.
Fermium (Fm) is in Group 7 in the Periodic Table.
The group no. of Lithium is 1 and its period number is 2.
According to the modern periodic table "Elements are the periodic function of their atomic number".They are arranged in increasing atomic no. in the periodic table.
Indium in the periodic table: group 13, period 5, atomic number 49.
Sodium, Na, is in group 1 period 3 on the periodic table.
group 1
18 group
It is group 8.
The periodic table of Mendeleev has 18 groups.
Oxygen is a non-metal in the group 6A of the periodic table.
Indium in the periodic table: group 13, period 5, atomic number 49.
A group in Periodic Table is the column of element in periodic table
