Do all atoms of an element have the same number of protons neutrons and electrons?

The number of protons in an atom is called its atomic number (Z). This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.

Do atoms have the same amount of protons and neutrons?

Atoms of a particular element must have the same number of protons but can have different numbers of neutrons. When an element has different variants that, while all having the same number of protons, have differing numbers of neutrons, these variants are called isotopes.

Do all elements have the same amount of atoms?

No. Although two such atoms are essentially chemically identical (they will chemically react in the same way), they are not completely identical. The nucleus of an atom contains neutrons and protons bonded tightly together. The same chemical element can have a different number of neutrons and still be the same element.

Can the same element have different amounts of neutrons and electrons?

Basic principles. Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.

Are all protons alike regardless of the atomic element?

All atoms of the same element have the same number of protons, but some may have different numbers of neutrons. For example, all carbon atoms have six protons, and most have six neutrons as well.

Do all atoms of the same element contain the same number of protons?

All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms. Atoms are neutral in electrical charge because they have the same number of negative electrons as positive protons (Table 2.4. 1).

Do atoms always have the same number of protons and electrons?

Atoms do not always contain the same number of electrons and protons, although this state is common. When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons).

Do all atoms of the same element contain the same number of neutrons?

All atoms of the same element have the same number of protons, but some may have different numbers of neutrons. Atoms of the same element that differ in their numbers of neutrons are called isotopes. Many isotopes occur naturally. Usually one or two isotopes of an element are the most stable and common.

Why do all atoms of an element have the same atomic number although they have different mass numbers?

All atoms of a chemical element have the same atomic number (number of protons in the nucleus) but may have different mass numbers (from having different numbers of neutrons in the nucleus). Atoms of an element with the same mass number make up an isotope of the element.

Do all atoms of the same element have the same number of electrons?

In all electrically-neutral atoms, the number of electrons is the same as the number of protons. Each element, when electrically neutral, has a number of electrons equal to its atomic number.

Is the number of protons and neutrons always the same?

The number of protons in the nucleus of every atom of an element is always the same, but this is not the case with the number of neutrons. Atoms of the same element can have a different number of neutrons. These atoms are called isotopes, which are atoms of the same element that have a different number of neutrons.

Are all atoms of the same element the same?

Besides, are all atoms of one element the same? Yes, all things are made of atoms, and all atoms are made of the same three basic particles – protons, neutrons, and electrons. But, all atoms are not the same. You know that the number of protons in an atom determines what element you have.

What is the difference between mass number and atomic number?

An element’s atomic number is equal to the number of protons in the nuclei of any of its atoms. The mass number of an atom is the sum of the protons and neutrons in the atom. Isotopes are atoms of the same element (same number of protons) that have different numbers of neutrons in their atomic nuclei.

What is the difference between isotopes and new elements?

Isotopes are variants that have differing numbers of neutrons. However, when the proton number changes (through bombardment in a particle accelerator or through radioactive decay), the differing proton number makes it, by definition, a new element. For example, carbon-12 and carbon-14 are isotopes containing different numbers of neutrons.
