Why are atoms so picky on who they bond with

Explanation:

Atoms are not really picky. They actually bond with other atoms to form an octect state. Let's take an example of an atom with, say, 2 valence electrons. This atom will have to bond with an atom which has 6 valence electrons to reach its octect state (6 + 2 = 8 =》 octect state is from L shell and above).

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
