What characterized a radioactive atom?
Its nucleus is unstable.
What happens if an atom is too ionized?
If your atom is too ionized, it will likely zip away from you and attach itself to a nearby atom or molecule. An atom becomes radioactive when its nucleus contains too many or too few neutrons. Try to keep the same number of neutrons and protons as you build your atom. If the imbalance is too great, radioactive decay will occur.
What is the substance that is smaller than an atom?
There are a few substances smaller than the atom, they're called sub-atomic particles and include things like protons, neutrons, electrons, photons, quarks etc.
What close distance to keep protons and neutrons together in the nucleus of an atom?
The distance is of few femtometres.
What is Found in the nucleus of the atom?
Protons and Neutrons are the main fundamental particles but physicists and nuclear chemists also believe that there are many other minor particles eg neutrinos, quarks, muons, positrons to mention a few. Higgs-boson particles??
How many protons and neutrons are there in the element scandium?
21 protons and 24 neutrons in the only stable for. But there can be as few as 15 and as many as 39 neutrons.
How is material made?
An atom (Protons, Neutrons, & Electons) is your basic building block. Add a few atoms together, and you get a molecule. Combine a few trillion molecules, and you get material.
What is Jerome Isaac Friedman's model of atom?
its a few circles with protons, electrons, and neutrons in them, and inside the protons are quarks. ur welcome
The region in an atom that contains most of the mass is called?
Most of the atom's mass is concentrated in the nucleus.
What are the primary factor determining whether or not an atom is stable or unstable?
I, too, also had this questions. After SEVERAL minutes of surfing the world wide web, I found that it is the number of neutrons that determine whether a nucleus is stable or unstable. I hope this helps you! ;)
How does nitrogen radioactive differ from a stable atom?
Chemically there is no difference between radioactive nitrogen and stable nitrogen. Both will react the exact same way in all chemical reactions. The only difference between the two is the number of neutrons in the nucleus. This means the only difference is mass. If the nitrogen atom has too many neutrons, it will most likely give off a beta particle. The beta particle shoots out from one of its neutrons. That neutron then becomes a proton and the nitrogen becomes oxygen. If the nitrogen atom has too few neutrons, a proton in its nucleus may capture one of its own electrons and turn into a neutron. This would then turn the nitrogen atom into a carbon atom.
Does an atom always have the same number of neutrons and protons?
No. It is possible for one atom of an element to have a different number of neutrons than another atom of the same element. For example, H usually has no neutrons, but deuterium has 1 neutron. An atom with a different number of neutrons is called an isotope.
