what are the difference between atomic number?
150211
The major difference between atomic number and mass number is that the atomic number states the number of protons present in an atom whereas, the mass number indicates the total of the number of protons and the number neutrons present in an atom.

Since an atom of one element can be distinguished from an atom of another element by the number of protons in its nucleus, scientists are always interested in this number, and how this number differs between different elements. The number of protons in an atom is called its atomic number (Z).

The atoms of different elements have different numbers of electrons, protons, and neutrons. Every element is unique and has an atomic number.

The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.

The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus. In an uncharged atom, the atomic number is also equal to the number of electrons. The sum of the atomic number Z and the number of neutrons N gives the mass number A of an atom.

The atomic number is the amount of protons present in the atom. Because of that, we can say that the atomic number represents the positive charge of the atom. As the positive charge of the atom increases the atomic radius decreases because the positive charge will bring electrons closer to the nucleus.

The atoms of different elements differ in the number of protons that are found in their nuclei. The number of protons in an atom's nucleus is called the atomic number. ... The number of protons in an atom's nucleus is called the atomic number. All atoms of the same element have the same atomic number.

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

Number of protons in the nucleus of an atom. Atomic number also specifies a number of electrons, which is equal to a number of protons. Atomic numbers are equivalent to element numbers in periodic table. An atom or a molecule that lost or gained one or more electrons, and thus has an electric charge.

Atomic Number and Mass Number While the mass number is the sum of the protons and neutrons in an atom, the atomic number is only the number of protons. The atomic number is the value found associated with an element on the periodic table because it is the key to the element's identity.
954181
Neutral atoms of an element contain an equal number of protons and electrons. The number of protons determines an element's atomic number (Z) and distinguishes one element from another. ... The number of neutrons can vary to produce isotopes, which are atoms of the same element that have different numbers of neutrons.

The atomic number (number at the top) is the amount of protons and the amount of electrons. So if an element has an atomic number of 5, you know that it has 5 protons and 5 electrons. The atomic mass (number at the bottom) is the amount of protons and neutrons added together.
1380484
The number of protons in an atom is the atomic number of that element. That's also the number of electrons, since atoms are neutrally-charged. Finally, the difference between the atom's weight and the atomic number is the number of neutrons. This is an incredible answer.

The atomic number of an atom is the number of protons (and usually, the number of electrons) in the atom. The atomic mass of an atom is the total number of protons and neu- trons in the nucleus of the atom.

We are shown that the atomic number is the number of protons in an atom. We see that the mass number minus the atomic number is the number of neutrons. We complete the atomic structure by explaining that atoms have the same number of protons and electrons.

An atomic number is the number of protons in a nucleus. The number of protons in a nucleus is a factor that introduces instability. All the elements beyond those found in nature were synthesized.

The atomic number is the number of protons in an atom of an element. In our example, krypton's atomic number is 36. This tells us that an atom of krypton has 36 protons in its nucleus.
