What happens to the atomic number and mass number of a nucleus when it captures an electron?
Since the actual weight of an atom is extremely small, a more convenient way of designating the relative mass of the various atoms is the atomic weight. The atomic weight of an atom was originally defined as the sum of the number of its protons and its neutrons. Unfortunately, this idea proved not valid as exact measurements of the actual weights of the various elements and sub-atomic particles were made. The new definition of an Atomic Mass unit is that it is 1/12 of the atomic weight of Carbon-12. Most listing of elements include isotopes to display an average atomic weight.
What else can I help you with?
A(n) is described as a nucleus of protons and neutrons surrounded by an electron cloud.?
Atomic number is the equivalent of the number of protons in an atomic nucleus.
What is the Atomic size of oxygen?
The atomic size of oxygen is approximately 60 picometers (pm). The atomic size refers to the distance from the nucleus to the outermost electron shell in an atom.
According to atomic theory electrons are usually found?
According to atomic theory, electrons are usually found in energy levels or shells surrounding the nucleus of an atom. They exist in specific orbits around the nucleus and are associated with specific energy levels.
When atoms gains electrons what happens to the atomic radius?
The negative ionic radius is larger than the neutral atomic radius
What is the atomic core of potassium ion?
The atomic core of a potassium ion consists of 19 protons and typically 20 neutrons, as potassium usually has an atomic number of 19. This gives the potassium ion a net positive charge of +1 due to the loss of one electron, balancing the charge of the 19 protons.
What happens to the identity of the atom when an electron leaves the nucleus?
Electrons are not part of the atomic nucleus.
What atomic particles are outsice the nucleus?
The electron.
The particle that orbits the nucleus in an atom is the?
The sub-atomic particle that orbits the nucleus in an atom is called an electron.
What is the name of the particle that orbits the nucleus of an atom?
The electron is the sub-atomic particle that orbits the nucleus of an atom of matter. For anti-matter the sub-atomic particle that orbits the nucleus is the anti-electron (positron).
What do you call the particle that orbits an atomic nucleus?
That particle is an electron.
What kind of sub-atomic particle does not make up the nucleus of the atom?
The proton and the neutron make up the nucleus, as the electron orbits the nucleus in the electron cloud.
When a radioactive isotope emits a its atomic number increases?
When a radioactive isotope emits a beta particle (high-energy electron), a neutron in the nucleus is converted into a proton. This causes the atomic number of the nucleus to increase by one because a proton has a positive charge and changes a neutron to a proton increases the atomic number.
What are sub-atomic?
Subatomic particles are protons and neutrons, which are found in the atomic nucleus, and electrons, which are found in the electron cloud surrounding the nucleus.
Subatomic particle that circles an atoms nucleus?
Electrons orbit the atomic nucleus in an electron cloud.
Of atomic structure describe the most probable location of an electron in relation to the nucleus of an atom?
In a shell at a distance form the atomic nucleus. The Electron Cloud
A(n) is described as a nucleus of protons and neutrons surrounded by an electron cloud.?
Atomic number is the equivalent of the number of protons in an atomic nucleus.
What is the negative paticle in orbit around an atomic nucleus?
that would be an electron
