How do you find the group number of neon?
Neon is a chemical element with symbol Ne and atomic number 10. It is in group 18 (noble gases) of the periodic table.
What is group number and periodic number?
Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.

What is group period?
The columns of the periodic table are called groups. Members of the same group in the table have the same number of electrons in the outermost shells of their atoms and form bonds of the same type. The horizontal rows are called periods.
What is a period number?
The period number is related to the number of electron occupied shells in the element and the period number is linked to its valence electrons.

What are Group 2A elements?
Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They are harder and less reactive than the alkali metals of Group 1A.
What is the general atomic number of neon?
Neon is a chemical element with atomic number 10 which means there are 10 protons and 10 electrons in the atomic structure. The chemical symbol for Neon is Ne. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. 58 pm.
What is the group name of element neon?
Neon (Ne), chemical element, inert gas of Group 18 ( noble gases) of the periodic table, used in electric signs and fluorescent lamps. Colourless, odourless, tasteless, and lighter than air, neon gas occurs in minute quantities in Earth’s atmosphere and trapped within the rocks of Earth’s crust.
What group name is neon in?
Neon is a member of the noble gas family. Other elements in this family includes helium, argon, krypton, xenon, and radon. These gases are in Group 18 (VIIIA) of the periodic table.
What is the common name of neon?
The name neon comes from the Greek word “neos” which means “new”. There are three known stable isotopes of neon including neon-20, neon-21, and neon-22. The most common is neon-20 which makes up about 90% of the naturally occurring neon.
