Yes, that is a characteristic of an atom.
What? Please make this clearer.
Metals are the pure substances by and show only characteristic properties of metals while a metalloid is an element which show some properties of metals and some properties of non metals as Aluminium, Zinc and Tin.
Different periodic tables show different information about an atom's properties. On the normal periodic table you can read the atomic number, which is the value of the number of protons in the nucleus.
This is the Lewis dot notation.
Chemical properties of a element is governed by ELECTRONIC CONFIGURATION of that element. As isotopes of same element have identical electronic configurations, their chemical properties are same.
Silicon.
What? Please make this clearer.
Silicon.
The number of electrons in isotopes is identical.
I don't know. I'm asking YOU that question.
An element can show an excited state when it casts off extra energy. This process can occur when a collision occurs between an atom and a particle or if it absorbs a proton.

If you want to show that A is a subset of B, you need to show that every element of A belongs to B. In other words, show that every object of A is also an object of B.
