The total number of protons and neutrons in the nucleus of an atom, ie: the mass of the atom.
The number of protons in the nucleus of an atom. It uniquely defines an element.
The characteristic number of protons per atom of an element. Used as an identifying attribute.
Number assigned to an atom corresponding to the number of protons in its nucleus.
The number of protons in each atom of a particular element.
a-TOM-ic NUM-ber The number in an element's box in the periodic table that indicates number of protons or electrons. 33
The number of positive charges on the nucleus of an atom, and in a neutral atom the number of orbital electrons.
The atomic number of an atom indicates how many protons it contains. Atomic Structure
For a chemical element, the number of protons within the atomic nucleus.
Number of protons contained in the nucleus of an atom.
indicates the number of protons in an element
The atomic number corresponds to the number of protons in the nucleus of an atom of that element. It also corresponds to the number of electrons in the neutral atom.
The number of protons or positively charged mass units in the nucleus of an atom, upon which its structure and properties depend.
The number of protons in the nucleus of a particular element; the charge on the nucleus.
the number of protons in an atomic nucleus
the number of protons in the nucleus of an atom; each element has a unique atomic number.
The atomic number is the total number of protons in an atom. Each element has a unique atomic number, which is written on the periodic table above the symbol of each element.
The atomic number of an atom is the number of protons in the nucleus of the atom. Back to top of the page
A number representing the positive charge or number of protons in the nucleus of an atom.
the total number of protons found in a nucleus.
The atomic number of an element indicates its place in the periodic table of the elements. It is the number of protons in the nucleus of one of its atoms. Periodic table of the elements...
(symbolized Z): The number of protons in a nucleus. It determines the chemical properties of an element.
The number of protons in the nucleus of an atom. Symbol Z.
represented by Z, equals the number of protons in the nucleus of an atom
Number of protons in the nucleus of an atom. Compare mass number.
The number of protons in the nucleus of an atom. Since this number is different for each element, elements are listed on the periodic table of elements in order of atomic number.
The number assigned to each element on the basis of the number of protons found in the element's nucleus.
An integer that designates the position of an element in the periodic table of the elements; it equals the number of protons in the nucleus and the number of electrons in the electrically neutral atom.
Total number of protons (and hence electrons for a neutral atom) in an atomic nucleus.
The number of protons in the nucleus of an atom, also called the proton number. Radioactivity
The number of positive charges or protons in the nucleus of an atom.
The atomic number (Z) of an element is the number of protons in the nucleus of the atom. The periodic table
A number assigned to each element that identifies the number of protons in the nucleus of an atom.
the number of positive charges carried by the nucleus of an atom
Is the number of protons in an element. Changing the number of protons will change the element.
The number of protons in the nucleus of a neutral atom of a nuclide.
The number of protons in the nucleus of an atom equal to the number of electrons in a neutral atom.
number of protons in the nucleus of an atom; the number determines the element's position on the periodic table. All isotopes of an element have the same atomic number
The atomic number of an atom is equal to the number of protons that the atom contains. Atoms can have differing numbers of neutrons and electrons while still retaining the original characteristic properties of that atom. However, if an atom gains or loses a proton, in essence, it changes its atomic number and becomes an entirely new atom with new characteristics.
the number of protons and electrons in an atom of a specific element in the ground state.
A number, , associated with the number of protons in the nucleus of an atom. Every element can be defined in s of its atomic number, since every atom of a given element has the same number of protons.
nbspThe number of electrons in a neutral atom.
In chemistry and physics, the atomic number (Z) (also known as the proton number) is the number of protons found in the nucleus of an atom. In an atom of neutral charge, the number of electrons also equals the atomic number.
