To find the amount of atoms in a mole you will use Avragadro's constant. So 2.8 x 6.02 x 10^23 (2.8x 6.02 ten to the power of 23)
2.8x 6.02 10^23
Answer:
<h3>Reactivity is the ability of matter to react chemically with other substances. Flammability is the ability of matter to burn.</h3>
It is the electron sharing.
electronegative element + electronegative element

Explanation:
The atom shown in the image has 2 core electrons.
Electrons are the negatively charged particles within an atom. Therefore the total number of electrons surrounding the nucleus in the given specie is 7.
So;
We have 2 core electrons
And 5 valence electrons
The core electrons are the inner orbital electrons.
The valence electrons are the outermost electrons.
