When two hydrogen atoms pair together, they form a single bond to achieve a complete duet which is a stable configuration.

When two halogens poir together,they form a single bond to achieve a complete octet which is a stable configuration

When two oxygen atoma pair together, they form a double bond to achieve a complete octet which is a stable configuration

When two nitrogen atoms pair together, they form a triple bond to achieve a complete octet which is a stable configuration

Explanation:

The tendency of atoms to achieve a noble gas configuration that is eight valence electrons is said to be octet rule. This is done to attain noble gas configuration and stability.

In order to attain stability the atoms tends to have eight electrons in its valence shell which can be obtained by either by sharing of electrons or complete transfer of electrons.

Hydrogen (H:1s^1) has one valence electron each, so sharing of electrons result in formation of single bond and the same electron configuration as the Helium and thus complete its duet.

Halogens (F:1s^22s^22p^5) have 7 valence electron each, so sharing of electrons result in formation of single bond. The stable noble gas configuration is attained and thus complete its octet.

Oxygen (O:1s^22s^22p^4) has six valence electrons each, so sharing of two electrons result in a double bond. The stable noble gas configuration is attained and thus complete its octet.

Nitrogen (N:1s^22s^22p^3) has 5 valence electrons, so sharing of three electrons result in a triple bond. The stable noble gas configuration is attained and thus complete its duet.

Answer from: Quest

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

Will give imagine you are given a mystery element. it is, however, a discovered and known element. you may perform a maximum of two observations or tests to determine its identity. time and money is critical, so you need to prioritize your tests. if you can get by with a single test, you get 100 super-geek points from your research lab team. pick your two tests, number them as #1 and #2, and justify why you think these two will certainly be enough (and why the first might well be enough all by itself.) the available tests are classification into metal, non-metal, or metalloid, count of valence electrons, count of electron shells, atomic radius (error range: +/- 1 pm), electronegativity (error range: +/- 0.1), first ionization energy (error range: +/- 10 kj/mole), melting point (error range: +/- 10 c), and boiling point (error range: +/- 20 c).
