How do the masses of the protons and the neutrons compare to the mass of the electrons?
If we give them relative numbers, the proton has a mass of 1.0073, the neutron has 1.0087 and the electron has 5.486 X 10 to negative 4.
What else can I help you with?
What subatomic particles could be changed without changing which element the atom?
You are probably referring to neutrons which are often found within the nucleus of an atom in numbers different from the protons. An atom of the element carbon, for instance, normally consists of 12 protons, 12 electrons and 12 neutrons. However, an isotope of carbon known as C13 consists of 12 protons, 12 electrons and 13 neutrons.
What do neutrons and protons have in common?
Neutrons and protons are both subatomic particles found in the nucleus of an atom. They have similar masses and are both composed of smaller particles called quarks.
What statement bout subatomic particles is not true?
"All subatomic particles have the same mass" is not a true statement, as different subatomic particles, such as protons, neutrons, and electrons, have different masses and charges.
What are two ways that a proton and a neutron are similar?
Protons and neutrons are both subatomic particles found in the nucleus of an atom. They have approximately the same mass, with protons having a positive charge and neutrons being electrically neutral.
Why do different metals of the same size have different masses?
Different metals have different atomic masses due to the number of protons, neutrons, and electrons in their atoms. This leads to variations in the density of the metals. Thus, metals of the same size can have different masses based on their atomic structure and density.
The atomic mass of an atom is determined by the combined masses of its what?
The atomic mass of an atom is determined by the combined masses of its protons, neutrons, and electrons. While electrons contribute very little to the atomic mass, the protons and neutrons, found in the nucleus, account for the majority of an atom's mass.
What is the mass of an atom mainly determined by?
The sum of masses of protons, neutrons and electrons.
What is the mass of an atom found by?
The mass of an atom is primarily determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass since electrons have negligible mass. The exact mass of an atom can be found by adding up the masses of its protons, neutrons, and electrons.
Do electrons neutrons and protons have essentially the same mas?
No, Protons and Neutrons have similar masses, but one electron is equal 1/1836 of a proton in mass.
How do the masses of one electron compare to the masses of protons and neutrons?
mass of electron = 1/1836 mass of proton (or neutron)
How do you get atomic mass?
Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom.--> Atomic Mass = protons + neutrons
What particles make up the mass of an atom?
The number of protons
All of the mass of an atom is due to the?
The mass of an atom is the sum of the masses of protons, neutrons and electrons.
What is the atomic mass composed of?
Atomic mass is composed of the mass of protons, neutrons, and electrons within an atom. Protons and neutrons reside in the nucleus of the atom, while electrons orbit around the nucleus. The sum of the masses of protons and neutrons is the primary contributor to the atomic mass.
Why don27t elements in the periodic table have whole numbers for their atomic masses?
Because the masses of protons, neutrons and electrons are not whole numbers.
Atomic mass of an atom is determined by the combined masses of?
Atomic mass of an atom is determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass, as they are much heavier than electrons. The atomic mass is usually given in atomic mass units, where 1 unit is defined as 1/12 the mass of a carbon-12 atom.
What information does the atomic mass of an elemt provide?
the number of protons and neutrons in an atom. Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom. --> Atomic Mass = protons + neutrons
