Answer:
Connection between the sodium and chlorine atoms are Ionic
Explanation:
Ionic bond is defined as the bond formed between two atoms by the complete transferring of electrons. It is type of chemical bond that generates two oppositely charged ions i.e Anion (-ve charge) and cation (+ve charge).
Metals that has 1, 2 or 3 electrons in its valence shell losses valence electrons and become positively charged cation. These electron attracted by the non-metals to form bond and become negatively charged anion. In this way, ionic bond is generated between 2 atoms.
Sodium is a metal with 1 electron in its valence shell. Chlorine is a non-metal with 7 less electrons (need 1 more to complete its valence shell to stabilize) in its valence shell. When sodium comes in contact with chlorine, it losses its one valence electron and become cation with +1 charge. This electron is accepted by chlorine and become anion with -1 charge. In this way ionic bond is formed between sodium and chloride.
Na⁺ + Cl ⁻⇒ NaCl
It's the natural tendency of things to keep going unless there's something trying to stop them.
It's usually called "inertia".
Don't get the idea from all of this that things stop unless there's something to keep them going. The truth is exactly the opposite: Things keep going unless there's something to make them stop.

Answer:
Explanation:
Notice that in the periodic table, the atom with 13 protons is the aluminum, whose chemical symbol is; .
When it is neutral (same number of protons than orbital electrons) there is nothing particular added to its symbol, but when it has lost 3 electrons, now the charges of the nucleus compared to such of the orbits are not in balance any more, because there are three positive charges unpaired. Now it is an ion, and the way to represent it is to add on the upper right of its symbol, a a "3+" representing the charge imbalance:
