Choose The Correct Definition Of An Atom's Atomic Number.

Choose The Correct Definition Of An Atom's Atomic Number.. In this example the atomic number is 17 and the mass number is 35. Because the mass of electrons is small relative to that of a proton or neutron, the mass number approximates the atomic mass.

Thus the atomic number of na atom = number of electrons = number of protons = 11. Effective atomic number (ean), number that represents the total number of electrons surrounding the nucleus of a metal atom in a metal complex. If given 14 6 c, then the atomic number will be the whole number which is smaller of the two numbers.

[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. The atomic number determines which element an atom is.

I believe the answer is that the atomic number is the number of protons in the nucleus of an atom.an atom is the smallest particle of an element that can take part in a chemical reaction. For example, any atom that contains exactly 47 protons in its nucleus is an atom of silver.

The Proton Number Is Shown Below The Chemical Symbol, And The Mass Number Is Shown Above.

An atom’s atomic number is the number of protons it has in its nucleus. It is the total number of protons in the atom’s nucleus. The protons and neutrons make up the nucleus of the atom, which is surrounded by the electrons belonging to the atom.

An Atom’s Atomic Number Is The Number Of Neutrons It Has In Its Nucleus.

An atom's atomic number is the number of electrons it has in its nucleus. The atomic number of an atom is equal to the number of protons in the nucleus of an atom or the number of electrons in an electrically neutral atom. Together, the number of protons and the number of neutrons determine an element’s mass number:

If Given 14 6 C, Then The Atomic Number Will Be The Whole Number Which Is Smaller Of The Two Numbers.

Atomic mass is denoted by a. Atomic number = number of protons. Atomic mass is the mass of an atom when the mass is expressed in u, the mass of a proton and of a neutron are both approximately one.

For This Reason, It's Sometimes Called The Proton Number.

The symbol z comes from the german word zahl, which means number of numeral, or atomzahl, a more modern word which means atomic number. An atom's atomic mass number is the number of protons plus the number of neutrons. An atom's atomic number is the number of protons it has in its nucleus.

In Calculations, It Is Denoted By The Capital Letter Z.

The atomic number is simply the number of protons in an atom. Choose the correct conditions, under which two atoms are different isotopes of the same element. An atom contains nucleus and the energy levels , the nucleus contains the protons and the neutrons while the energy levels contain electrons.
