Fundamental Subatomic Particles 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 mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

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 number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

Answer Key The number of protons an atom has is called its atomic number, which decides what kind of atom it is. Changes in the number of neutrons make an isotope, and changes to the number of electrons make an ion. (A) They are made up of subatomic particles called protons, electrons and neutrons.

There's also the nucleus. 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. We refer to the atoms of the same element with different numbers of neutrons as "isotopes".

The atomic number is the number of protons in an atom of an element. ... Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons. Electrons are arranged around atoms in a special way.

Normally, the number of electrons is equal to the number of protons, which makes atoms electrically neutral. The number of protons in an atom is the defining feature of an atom. It's what makes one element different from another. The number of protons in an atom is called its atomic number.

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.

These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. ... Because different isotopes have different numbers of neutrons, they do not all weigh the same or have the same mass. Different isotopes of the same element have the same atomic number.

An atom contains equal numbers of protons and electrons . Since protons and electrons have equal and opposite charges , this means that atoms are neutral overall.

atoms and elements?) ... A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron.

Atoms of different elements have a different mass and volume. ... Atoms have protons, neutrons, and electrons. Atoms lack the same number of electrons. Atoms have unique properties that define them.

Unlike the number of protons, which is always the same for all atoms of the same element, the number of neutrons can be different. Atoms of the same element with different numbers of neutrons are known as isotopes.

How are atoms of the same element alike? The are alike in that they always have the same number of protons, and an uncharged atom will have the same number of protons. The number of neutrons may change, but that usually doesn't change the chemistry.

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.

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.

Protons, neutrons, and electrons are the three main subatomic particles found in an atom. The element Na has 11 protons, 11 electrons, and 12 neutrons for a total of 34 subatomic particles.

An atom contains equal numbers of protons and electrons . Since protons and electrons have equal and opposite charges, this means that atoms are have no overall electrical charge.
