When an atom loses or gain this type of particle the mass nbr changes?
electrons
What happen when an atom forms an ion?
For an atom to form an ion, it has to either gain or lose one or more electrons. Usually this happens during a chemical reaction, when an element gains or loses electrons to achieve noble gas configuration.
When it loses two electrons to become a calcium ion what is it's new mass?
38 amu EDIT: This answer is INCORRECT. Electrons do not have significant mass.
What do you think happens to the side to the size of an atom when the atom loses an electron?
The atom would stay the same size because it would still have the same amount of energy levels. The mass of the atom would be slightly less though.No, an atom shrinks when loosing an electron.There are less electrons ('-'charges) left that are attracted by the same number of protons ('+'charges) in nucleus, so the atraction per electron is stronger.
When an atom loses an electron the mass of the at om?
The mass doesn't change because electrons are so light that its mass is not included in the AMU.proton = 1 amuneutron = 1 amuelectron = ~1/1837 amu
What happens to an atom in terms of atomic mass and weight when it loses one particle?
If an atom looses an electron, neither the atomic mass nor atomic weight change appreciatively. If it looses a proton or neutron, both atomic mass and atomic weight decrease by one and it becomes an atom of a different element (on loss of a proton), or a different isotope of the same element (upon loss of a neutron).
Is the change in mass significant when an object gains or loses electrons?
No, the change in mass is generally not significant when an object gains or loses electrons because electrons have a very small mass compared to protons and neutrons in the nucleus. The change in mass from gaining or losing electrons is usually negligible.
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.
What are the subatomic particles that are transferred to form ions?
Ions are formed by the gain OR loss of an electron.
Where is almost all of the mass in an atom is located?
Approximately all of the atom's mass is in the nucleus. The electrons contribute almost zero.No atom has more than 100 electrons, but eachproton or neutron in the nucleushas the mass of more than 1,800 electrons.
Why is it not necessary to include electrons when determining the mass of an atom?
While electrons do technically have a measurable mass, the proportion of the overall mass of the atom contributed by the electrons is negligible. The protons and neutrons in the nucleus contribute the vast majority of the mass of the atom and thus are the only parts considered.
What happens if an atom of uranium loses a proton?
If an atom of uranium loses a proton, it becomes an atom of an element with one less proton in its nucleus, known as an isotope of a different element. This change can alter the atomic number, mass number, and chemical properties of the atom.
