Atom does not have to have equal numbers of protons and?
neutrons in order to be stable. The number of protons determines the element's identity, while the stability of the nucleus is influenced by the balance of protons and neutrons. Isotopes can have different numbers of neutrons while maintaining the same number of protons.
Atomic masses of any two elements contain the same number of?
protons and neutrons. This is because the atomic mass of an element is calculated by adding the number of protons and neutrons in the nucleus of an atom. The number of protons determines the element's identity, while the number of neutrons affects its stability.
What subatomic particle number determines the identity of an element?
The number of protons, which is the atomic number of an element, determines the identity of an element.
Do the protons or neutrons Equal the atomic number?
The atomic number of an element is defined by the number of protons in its nucleus. Therefore, protons equal the atomic number, while neutrons do not; instead, the number of neutrons can vary among isotopes of the same element. The atomic number determines the element's identity, whereas the total number of nucleons (protons and neutrons) gives the atomic mass.
What is the difference between mass number and atomic number?
The mass number is the total number of protons and neutrons in an atom's nucleus, while the atomic number is the number of protons in the nucleus. The mass number determines the atom's mass, while the atomic number determines the element's identity on the periodic table.
Which element determines the identity of an element?
The number of protons in the nucleus determines what element it is. There can be different isotopes that have more or less neutrons, and there can be ions meaning they're positively or negatively charged which means they've lost an electron or gained an extra one.
Does an atom retain the chemical identity of an element?
An isotope is an atom that contains a different number of neutrons. In order for an element to change there has to be a different number of protons.
What is the identity of an element with 5 protons 7 neutrons and 5 electrons?
Five protons makes this the element boron. The number of protons is the atomic number, and determines the identity of an element. This example would be the boron-12 isotope because it contains 5 protons and 7 neutrons.
How many protons neutrons and electrons are in elements?
The number of protons in an element is its atomic number, which determines its identity. Neutrons can vary for different isotopes of the same element. Electrons equal the number of protons in a neutral atom.
How do you determine the numbers of subatomic particles in an atom based on its identity?
The number of protons in the nucleus determines the atom's identity. This is the atomic number on the periodic table. The number of electrons in a neutral atom is equal to the number of protons. Neutrons can vary, but the atomic mass on the periodic table provides an average number of protons and neutrons in an atom.
Which of the following is unique for any given element A the number of protons B the number of neutrons C the charge on the electrons D the mass of the neutron?
its atomic numberthe number of neutrons
What is the particle that identifies a atom?
The number of protons in an atom's nucleus determines its chemical identity.
