you can identify the properties of an element by studying its_____ on the ... between metals and nonmetals on the periodic table are the _____ which have ...
Explanation:
If you are looking for a one specific electron you will have 90% chance of finding it in an area within the atom electron clouds.
According to the wave mechanical or electron cloud model of the atom, postulates that the atomic orbital is a region in space where there is a very high probability of finding an electron.
The term "electron cloud" is just another term used for "atomic orbital".
Since electrons reside in orbitals, if you are looking for a one specific electron you will have 90% chance of finding it anywhere within the electron clouds. This would make mathematical sense as the probability of finding an electron within the electron cloud can never be 100%.

Answer:
Zero with the subscripts, +2 without them.
Explanation:
Hello!
In this case, since we consider that two silicon are bonded with four oxygen atoms to form silicon oxide according to the following chemical equation:
It is also possible to realize it can be simplified to obtain:
Which means that the total charge with the subscripts is zero, and without the subscripts +2 (+4-2).
Best regards!
In alpha and beta decay the parent element and the daughter element will be different isotope and not the same.
This is because as alpha particles comes out; the new element will have two less in atomic number; that is the atomic number will reduce by two and the mass number will reduce by four. While in a beta particle decay, the new element will have one higher in atomic number; that is the atomic number will increase by one.
