Isotopes
.
An Isotope
is an atom that has gained or lost NEUTRONS. If an atom gains/loses neutrons, charge is not affected.
What do you call an atom that has gained or lost electrons?
When an atom gains or loses an electron, it attains a net charge and becomes an ion. When electrons are lost (or donated), the resulting ion is called
cation
. When electrons are gained, the resulting ion is called an anion.
What is it called when an atom loses or gains?
When an atom gains/loses an electron, the atom becomes charged, and is called
an ion
. Gaining an electron results in a negative charge, so the atom is an anion. Losing an electron results in a positive charge, so atom ion is a cation.
What is it called when an atom gains an electron?
Ionization
is the process by which ions are formed by gain or loss of an electron from an atom or molecule. If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation).
What is lost if you lose a neutron from an atom?
As only a neutron is lost by this process
the number of protons remains unchanged
, and an atom does not become an atom of a different element, but a different isotope of the same element. Neutrons are also produced in the spontaneous and induced fission of certain heavy nuclides.
How would you describe an oxygen atom that has lost an electron?
When an atom loses an electron it
loses electric charge as electrons are negative
. The atom becomes more positive and less negative. This is Oxidation. When an atom combines with Oxygen the atom forms a bond with Oxygen.
What is the smallest unit of matter?
atom
, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry.
Can protons be gained or lost?
The only two ways by which atoms
lose
protons is through radioactive decay and nuclear fission.
What is losing electrons called?
The loss of electrons is called
oxidation
. The gain of electrons is called reduction. … The atom that loses electrons is oxidized, and the atom that gains electrons is reduced.
What happens when a hydrogen atom loses an electron?
A hydrogen ion
is formed when a hydrogen atom loses an electron and therefore becomes positively charged (it has a charge of +1). A hydrogen atom is therefore often referred to as just a proton, as it is left with only one proton and no electrons, as a H atom only has one of each.
What happens to an atom when it becomes an ion?
An atom becomes an Ion (a) if
it gains one or more electron(s)
or (b) if it loses one or more electron(s). When it gains electrons it becomes negatively charged and is called an anion. When it loses electron(s) it becomes positively charged and is called a cation.
Why is an atom electrically neutral?
Electrons have electric charge of -1 and
the number of electrons in an atom is equal to the number of protons
. … Heavier atoms tend to have more neutrons than protons, but the number of electrons in an atom is always equal to the number of protons. So an atom as a whole is electrically neutral.
When an atom gains one or more electrons?
Answer: An atom that gains or loses one or more electrons is called
an ION
. A positive ion is called a CATION and a negative ion is called an ANION.
How does removing a neutron change the mass?
Neutrons do not carry an electrical charge so adding or removing them from the nucleus does not change the electrical charge of the nucleus. It does, however, change the mass of the nucleus.
When an atom loses a proton it is no longer the same element?
True: The atom is 10,000 times larger than the nucleus. true: When an atom loses a proton, it is no longer the same element. Correct: When an atom loses an electron, it is still the same element. false: Isotopes have the same number of neutrons, but different numbers of protons.
Can Neutronium be dark matter?
Dark matter, in contrast to particles like the neutron, must be
stable for
at least hundreds of billions of years, so it absolutely cannot decay away on typical timescales that the d* particle decays on.
