which two types of particles are present in equal numbers in an atom?
529532
Answer and Explanation: The two particles in the atom that are equal in number are the protons and electrons. The protons are located in the nucleus along with neutrons.

There are two types of particle in the nucleus of an atom: the proton and the neutron. The proton has a positive charge and a large mass (1800 times more than an electron – see table 1). The number of protons in a nucleus is the same for all the atoms of a particular element.

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. ... All isotopes of a particular element have the same number of protons, but can have different numbers of neutrons.

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

Atomic Number. 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. For example, carbon's atomic number (Z) is 6 because it has 6 protons.

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).

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.

The proton identifies an atom as that of a particular element. The atomic number is equal to the number of protons in the nucleus of an atom.

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.

A. Atomic Number Equals Electrons or Protons The atomic number equals the charge on the nucleus. It therefore also equals the number of protons in the nucleus and also equals numerically the number of electrons in the neutral atom. The atomic number has the symbol Z.

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.

The atomic number of an element is the number of protons in its nucleus. Neutrons are neutral particles having a mass slightly greater than that of the proton. Different isotopes of the same element contain the same number of protons but differing numbers of neutrons.

Atoms of the same element (i.e., atoms with the same number of protons) with different numbers of neutrons are called isotopes. Most naturally occurring elements exist as isotopes. For example, most hydrogen atoms have a single proton in their nucleus.

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.

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). The total electric charge of the atom is therefore zero and the atom is said to be neutral.

Mass number. The mass number of an atom is its total number of protons and neutrons. Atoms of different elements usually have different mass numbers , but they can be the same.

Atomic number is equal to the number of protons and number of electrons in the nucleus . Mass no is equal to the sum of the number of protons and neutrons in the nucleus of an atom. What is atomic mass?
