This depends on the half-life of the atom
Carbon is a chemical element with an atomic number of 6 and an atomic mass of about 12.011 atomic mass units.
The mass does not change much. The Atomic number will increase though.
Atomic mass includes the total mass of protons, neutrons, and electrons in an atom. Since protons and neutrons contribute significantly to the mass of an atom, atomic mass is generally greater than atomic number, which represents the number of protons in the nucleus. Electrons have a much smaller mass compared to protons and neutrons, so they have less impact on the overall atomic mass.
The mass of an atom depends on the nucleus because the nucleus contains the majority of the atom's mass in the form of protons and neutrons. Electrons, which orbit the nucleus, have a much smaller mass compared to protons and neutrons. The mass of an atom is essentially the combined mass of its protons and neutrons in the nucleus.
The atomic mass of an atom is primarily made up of protons and neutrons, which are collectively known as nucleons. Protons, positively charged particles, and neutrons, neutral particles, reside in the nucleus of an atom. Electrons, which are negatively charged, contribute negligibly to the atomic mass due to their much smaller mass compared to protons and neutrons. Thus, the atomic mass is largely determined by the number of protons and neutrons in the nucleus.
The atomic mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.
The density of the nuclear mass is higher than that of the atomic mass because atoms are mostly empty space with the majority of their mass concentrated in the nucleus, which is extremely dense. The nucleus contains protons and neutrons tightly packed together, leading to a much higher density compared to the overall atomic mass spread out over the atom's volume.
Atomic mass is not a measure assigned to gross mass such as grams, kilograms, pounds, stones, tons etc.Atomic mass of an element is determined by the number of protons there are in the nucleus of that element.The amu (atomic mass unit) is standardized as 1/12 of the mass of an atom of Carbon
Yes, the atomic weight of the protons and neutrons in an atom (the 2 particles that make up the nucleus) is 1 for each of them. The other particle in an atom is an electron. The atomic weight of an electron is 1/1840 so it is often considered negligible.
When a nucleus emits an electron, the atomic number increases by 1 since the nucleus gains a proton. However, the mass number remains the same because an electron is much lighter than a proton or neutron.
If there is only 1 isotope then they are equal. Many naturally found elements have various isotopes (different numbers of neutrons in the nucleus). Each isotope has a diffent mass, so the measured atomic weight is an average.
Protons, neutrons, and electrons are atomic particles that carry mass. Protons and neutrons contribute most of the mass to an atom's nucleus, while electrons have a much smaller mass compared to protons and neutrons.
