Different isotopes of the same element have different numbers of neutrons, which indicates that neutrons do not determine an atom's identity. Since electrons can be lost or gained, or shared, electrons cannot determine an atom's identity. Only the number of protons of an element do not change.25-Oct-2015
What determines an atom identity?
The number of protons in the nucleus of an atom is its atomic number (Z). This is the defining trait of an element: Its value determines the identity of the atom. For example, any atom that contains six protons is the element carbon and has the atomic number 6, regardless of how many neutrons or electrons it may have.
What do neutrons determine in an atom?
The number of neutrons influences the element's mass; that is how isotopes of the same element differ.
Do electrons determine the identity of an atom?
Since electrons can be lost or gained, or shared, electrons cannot determine an atom's identity. Only the number of protons of an element do not change.
What determines the identity of an atom quizlet?
The identity of the atom is determined by the number of protons; an atom with five protons has different properties than an atom with six protons. small mass. We use a very small unit of mass to measure them, and this unit is called an atomic mass unit (amu).
Why do protons determine the identity of an atom?
Protons contribute to the mass of an atom and provide the positive charge to the nucleus. The number of protons also determines the identity of the element. Electrons have a negative charge. Since the atom is electrically neutral, the number of electrons must equal the number of protons.
What subatomic particle determines the identity of an atom?
The number of protons determines the element of the atom, the number of neutrons determines the isotope, and the number of electrons determines the ionization state. Answer 4: I would say the proton is the “boss,” since the number of protons determines the atomic number and therefore the chemical identity of the atom.
Which subatomic particle determines the identity of an atom quizlet?
a subatomic particle that has a positive charge and that is located in the nucleus of an atom; the number of protons in the nucleus is the atomic number, which determines the identity of an element.
Do protons neutrons electrons determine properties atom?
The number of protons along with the neutrons will help to determine the mass number of the chemical element. The number of protons will determine the number of the electrons present. This electron will determine the chemical properties of the element.
What is the one thing that determines the identity of an atom that is whether it is an oxygen atom or a carbon atom etc?
The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element.
