A synthesis reaction is a chemical process in which two dissimilar atoms interact to create a new substance or molecule.
The atomic number of the alkali metal sodium is 11. The valence electron in its outermost shell is positive (+1).
With the atomic number 17, chlorine belongs to the halogen family of elements. Its octet structure can only be completed with an electron.
Because of this, their bonding process is known as electrovalent or ionic bonding.
When 2 moles of sodium (Na) and 1 mole of chlorine (Cl) are combined, the following results:
2Na(s)Sodium+Cl2(g)Chlorine→2NaCl(s)Sodium Chloride
As a result of the foregoing process, we can infer that two sodium molecules are created when two sodium (Na) atoms interact with one molecule of chlorine gas (Cl2).

Whose discovery led to the discovery of the proton?
A. Dalton
B. Rutherford
C. Aristotle
D. Bohr
explain the three forces at work that hold an atom together
An atom is held together by three forces: the strong nuclear force, the electromagnetic force, and the weak nuclear force.
The strong nuclear force is the strongest of the three forces and is responsible for binding the protons and neutrons together in the nucleus of an atom. The strong nuclear force is a short-range force that acts only over a very small distance, and it is strong enough to overcome the repulsive forces between the protons, which are positively charged particles.
The electromagnetic force is the second strongest of the three forces, and it is responsible for binding the electrons to the nucleus of an atom. The electromagnetic force is a long-range force that acts over a larger distance than the strong nuclear force, and it is caused by the attraction between opposite charges (positive and negative).
The weak nuclear force is the weakest of the three forces, and it is responsible for certain types of radioactive decay, such as beta decay. The weak nuclear force is a short-range force that acts only over a very small distance, and it is much weaker than the strong nuclear force and the electromagnetic force.
Overall, the three forces at work that hold an atom together are the strong nuclear force, the electromagnetic force, and the weak nuclear force. These forces act at different ranges and with different strengths, but they all play a crucial role in maintaining the stability and integrity of an atom.
