The number of protons in an atom represents the atomic number of that particular atom. Find an answer to your question What does the number below each elements symbol represent. The atomic number identifies an element.
Because there is usually one isotope that is much more common on Earth rounding the atomic mass to the nearest whole number gives the atomic mass of that isotope and is called the atomic mass number. The atomic number of an element is equal to the number of protons in its nucleus. The atomic number is simply the number of protons in an atom.
An atomic number represent protons in an atom. The symbol Z comes from the German word zahl which means number of numeral or atomzahl a more modern word which means atomic number. The nucleus is composed of protons and neutrons.
For example on the periodic table sodium Na has an atomic number of 11 and an atomic mass of 22990. Atomic number represents the number of protons in the atomic nucleus of an atom of an element. The atomic number of a chemical element is the number of protons in the nucleus of an atom of the element.
The total number of protons in the nucleus of an atom is called the atomic number or the proton number of the atom and is given the symbol Z. What does the atomic number represent apex. What does the atomic number represent.

Choice They all have the same atomic mass. They all have the. Oct 26 2015 In ground state atoms both the number of protons and electrons.
What does the atomic number represent. The symbol for an atom can be written to show its mass number at the top and its atomic number at the bottom. For ordinary nuclei this is equal to the proton number np or the number of protons found in the nucleus for every atom of that element.
The fundamental unit of chemical matter. Noun an experimentally determined number characteristic of a chemical element that represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus and that determines the place of the element in the periodic table see Chemical Elements Table. Atomic mass unit amu A mass equivalent to one-twelfth the mass of a carbon-12 atom.
In calculations it is denoted by the capital letter Z. The average atomic mass. The atomic number equals the number of protons in an atom as well as the number of electrons in a stable electrically neutral atom it represents the identity of an element the simplest form of.
Isotopes are atoms with the same atomic number but distinct neutron numbers and hence distinct mass numbers. The modern periodic table is ordered by increasing atomic number. Atomic number definition the number of positive charges or protons in the nucleus of an atom of a given element and therefore also the number of electrons normally surrounding the nucleusAbbreviation.
The atomic number can be used to uniquely identify ordinary chemical elements. An atomic number represent protons in an atom. The first element in the periodic table is hydrogen which has an atomic.
Noun the uppermost point. The atomic number of an atom represents the number of protons found in the nucleus of that atom. It is the charge number of the nucleus since neutrons carry no net electrical charge.
