The first and the last choice is the same, aren't they?
Sodium Chloride is ordinary table salt
You have a small sodium atom with a positive charge Na+, and a larger chlorine atom with a negative charge, making it a Chloride ion, Cl-.
This ion formation has resulted from Na transferring one of its electrons to Cl. there opposite charges then attract them to each-other.
Because the electrons are transferred rather than shared, we know that the bond is Ionic, rather than covalent.
Most ionic compounds, if not all, are salts that form a crystal lattice structure, due to the opposite charges in the molecule.
Think of it like this
Na+—Cl-
Cl—-Na+
Na+—Cl-
That’s how the molecules attract and stick to each other. That would continue until you ran out of NaCl molecules.
Answer:
U could use the formula
Explanation:
To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6.02 x 10^23
Answer:
No idea
Explanation:
I'll tell u how to do it. You multiply by amidagros number. that is how many atoms you have. Your welcome.
