What is the valency of an atom of a mass number 25?
The only non-radioactive isotope with a mass number of 25 is magnesium-25. The valency of magnesium is 2.
What is the difference between a bonding electron domain and a non bonding electron domain?
bonding electrons are when the electron have the same number and the connect,like valence electrons. Non-bonding electrons are only possible when an atom is unstable, no more than 2 electrons or if the atom is an isotope. bonding electron pairs occur in a covalent bond between two atoms. they include one electron from each atom in the covalent bond. non-bonding pairs do not take part in bonding. they are the left over electrons in the outter shell of the atom.
At what point do isotopes stop decaying?
Isotopes do not stop decaying. The process of radioactive decay continues until the isotope reaches a stable state, which could be a different isotope or a non-radioactive element. The rate of decay can vary depending on the specific isotope.
What is the atomic mass of an oxygen atom?
The atomic mass of an oxygen atom depends on which isotope of oxygen you are referring to. The AVERAGE atomic mass is approximately 15.9994
Can you find out the number of electrons by adding protons and neutrons?
To find out the number of electrons in an element you must add the protons and neutrons and subtract that number with the atomic mass, this will determine the amount of electrons because the unknown element could be an isotope and have more than the normal amount of electrons of the non isotope element.
How is an isotope different from an atom?
Isotopes aren't mutually exclusive of an atom - that is, you don't have to be one or the other (in fact, it is both). An isotope of an atom is an atom that has an unusual atomic weight, usually caused by having a non-regular amount of neutrons (they don't change the charge, so you can shove as many in an atom as you want, within limits).
What is a antonym for isotope?
The antonym for isotope is non-isotope. An isotope refers to atoms of the same element with different numbers of neutrons, whereas non-isotope would refer to atoms of the same element having the same number of neutrons.
How long does an atom live?
It depends on which isotope of which element you are talking about. Carbon's isotope C-12 lasts forever because it is a stable, non-radioactive element. Carbon's other isotope, C-15, however, lasts only 2.5 seconds after it appears into existence. Therefore, because different isotopes of different atoms last different amounts of times, it is impossible to say how long an atom lives because there are so many different elements. However, if you take a look at the link provided, you can pick an element from any of those, scroll down the page a little bit, and there should be a data table. It tells how long that element's isotope lives.

How many electrons does Litium 7 have?
Lithium is a non metal element. There are 3 electrons in a single atom.
Would an atom with 60 protons and a mass number of 155 be stable?
An atom with 60 protons would be the element neodymium (Nd), which has atomic number 60. A mass number of 155 suggests it has 95 neutrons (155 - 60). Neodymium-155 is a stable isotope, so the atom would be stable.
Name 3 radioactive metals?
Most elements - metals and non-metals - have both stable and radioactivie isotopes. If an element is a type of atom, an isotope is something like a "sub-type". Two isotopes of the same element have the same number of protons, but a different number of neutrons.Most elements - metals and non-metals - have both stable and radioactivie isotopes.

Does a ion have the same electrons has a non-ionic atom?
No, an ion has gained or lost electrons, so it will have a different number of electrons compared to the non-ionic atom of the same element.
What element has 28 subatomic particles in the nucleus of one atom?
The only non-radioactive isotope with the specified properties is silicon-28, which constitutes more than 90 % of naturally occuring silicon.
What is the atomic mass of an oxygen atom?
The atomic mass of an oxygen atom depends on which isotope of oxygen you are referring to. The AVERAGE atomic mass is approximately 15.9994
