In quantum matter, all things in the world are made up of even smaller particles than the atom. These are called the subatomic particles: neutron, proton and electron. A beta particle is simply an electron. It is an electromagnetic particle or wave. Electromagnetic particles are high-energy particles that are emitted by the atom during radioactive decay. Since it is an electron, its charge must be -1 and it must come from outside the nucleus of the atom. From the choices, the answers would be:
<span>is electromagnetic energy
</span><span>has a -1 charge</span>
Answer:
number of Al atom =54÷27=2atom of Al. number of o atom = 160÷16=10 atom of o . =214U MASS of ALO2.
Answer:
D. Calculate the variations in the potions of the star due to movement of Earth in its orbit
A I think I could be wrong I’m not good at this
Explanation:
1) Atoms can not be subdivided. It has been changed as it is possible to divide an atom into Protons, Neutrons and Electrons as well as other smaller particles.
2) The regulations for the chemical mixture have always been altered to the rules for the chemical combination in the creation of organic compounds may be denied.
3)Atoms are of a particular element are identical in all respects i. e. they have same mass and similar properties.
It was modified. And according. to new search;
Atoms of the same element may not be always identical.
