The number of protons in the nucleus of an atom. In electrically neutral atoms, this number is also equal to the number of electrons orbiting about the atom's nucleus. The atomic number of an element determines its position in the Periodic Table. ...

Argon, chemical element, inert gas of Group 18 (noble gases) of the periodic table, terrestrially the most abundant and industrially the most frequently used of the noble gases. It is used in gas-filled electric light bulbs, radio tubes, and Geiger count
Here's a collection of useful and interesting argon facts. Argon is the noble gas with element atomic number 18 with element symbol Ar.
is the element that isatomic number2 on the periodic table. Each helium atom has 2protonsin its atomic nucleus. The atomic weight of the element is 4.0026. Helium does not readily form compounds, so it is known in its pure form as a gas. ...
What is the atomic number of scandium? How many valence electrons does vanadium have? What is the atomic number for tellurium? What is the atomic number of antimony? What is the atomic number for argon? What is the atomic number for manganese?
argonon,inert gas,noble gas- any of the chemically inert gaseous elements of the helium group in the periodic table air- a mixture of gases (especially oxygen) required for breathing; the stuff that the wind consists of; "air pollution"; "a smell of chemicals in the air"; "open a wind...
Atomic Number The atomic number of an element, denoted as Z, is equal to the number of protons inside the nucleus of an atom. In the periodic table, the elements are arranged in increasing atomic numbers. Answer and Explanation:1 Become a Study.com m...
For example, tellurium comes before iodine in the periodic table, even though its atomic mass is slightly greater. Such anomalies are due to the relative abundance of the "isotopes" or varieties of each element. All the isotopes of a given element have the same number of protons, but differ...
