is the atomic number the number of protons and electrons?
31492
The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. 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.

If the atom is neutral, the number of electrons will be equal to the number of protons. Remember! 1. Your mass number is the total number of neutrons and protons within the atom.

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 it contains. ... All the atoms of a particular element have the same atomic number. You just studied 6 terms!

The number of protons in an atom of an element is its atomic number . ... all atoms of a given element have the same number of protons. atoms of different elements have different numbers of protons.

Can an atom have a different number of protons and electrons? Yes. Each element has a specific number of protons that make up it's identity. However, electron count and configuration can change to make bonds, in elemental form, etc.
1417560
The atoms of different elements all have different numbers of protons. Meanwhile, the mass number of an atom consists of the total number of protons and neutrons it contains. An atom's mass number can never be smaller than its atomic number, and while it can be the same it is normally larger.

Atomic Numbers. In the modern periodic table, the elements are listed in order of increasing atomic number. The atomic number is the number of protons in the nucleus of an atom.
42761
The number of protons in the nucleus of an atom is known as the atomic number, Z. It is the same as the number of electrons around the nucleus of the electrically-neutral atom. The mass number of an atom is equal to the total number of protons and neutrons.
643166
The number of protons in an atom of an element is its atomic number . Remember that: all atoms of a given element have the same number of protons. atoms of different elements have different numbers of protons.

Elements are placed in order on the periodic table based on their atomic number, how many protons they have. In a neutral atom, the number of electrons will equal the number of protons, so we can easily determine electron number from atomic number.

Go to the Periodic Table of Elements and click on your element. If it makes things easier, you can select your element from an alphabetical listing. The atomic number is the number of protons in an atom of an element.

Fundamental properties of atoms including atomic number and atomic mass. The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons.
589718
Each atom, therefore, can be assigned both an atomic number (the number of protons equals the number of electrons) and an atomic weight (approximately equaling the number of protons plus the number of neutrons).
641034
The atoms of different elements have different numbers of electrons, protons, and neutrons. Every element is unique and has an atomic number. That number tells you the number of protons in every atom of the element. The atomic number is also called the proton number.

The atomic number (also known as the proton number) is the number of protons found in the nucleus of an atom. It is traditionally represented by the symbol Z. The atomic number uniquely identifies a chemical element. In an atom of neutral charge, atomic number is equal to the number of electrons.

Atomic Number. Indicates the number of protons in the nucleus. The atomic number defines an atom. All atoms of an element have the same atomic number. No two elements have the same atomic number.
