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.

∙ 9y agoWe make atomic number by number of protons in a atom. We make mass number by total of both protons and neutrons.

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.
How do you find a electron in a neutral atom?
Electrons are in a continuous movement around the atomic nucleus.
What is the atomic core of potassium ion?
The nucleus is an electron, but in the outermost shell (= valence electron). The atomic number (Z) of potassium is 19. Therefore its electron distribution is 1s2 2s2 2p6 3s2 3p6 4s The valence electron is 4s, so the nucleus is 1s2 2s2 2p6 3s2 3p6. The potassium ion, K+, has lost one of its outermost electrons, so it has the same electrons as the nucleus of K.
According to atomic theory electrons are usually found?
in the energy levels. energy levels are in the electron cloud.
6 The atomic number of oxygen is 8 because oxygen has?
The atomic number of oxygen is 8 because oxygen has 8 protons in its nucleus.The atomic number of a chemical element (also known as its proton number) is always the number of protons found in the nucleus of an atom of that element, and identical to the charge number of the nucleus. It is conventionally represented by the symbol Z.The Atomic Number is a count of how many Protons are present in an atom of an element.The element Oxygen has 8 Protons in its atomic nucleus and therefore has an Atomic Number of 8.Note: in an electrically neutral atom the number of electrons in the electron cloud exactly matches the number of Protons in the nucleus of the atom, therefore electrically neutral oxygen will also have 8 electrons.
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.
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).
The atomic radius to the distance from the nucleus of an atom to?
The atomic radius is the distance from the nucleus of an atom to the outermost orbital of 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.
The particle that moves around the nucleus is?
Electrons move around the atomic nucleus.
What do you call the particle that orbits an atomic nucleus?
That particle is an electron.
Where are the nucleus and electron cloud found in a atomic structure?
The nucleus is found at the center of the atom and the electron cloud is found orbiting the nucleus at fixed, quantified radii.
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?
a beta particle. the nucleus is made of protons (+) and neutrons. but neutrons can transform into an electron and a proton. when that happens in the nucleus, the proton stays in the nucleus while the electron shoots out at incredibly high speeds. that high speed electron is called a beta particle. the proton that stays is added to the other protons to increase the atomic number
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 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.
