Supervisory responsibilities tend to bring out a person's negative side. true or false?
The metals and non metals which tend to form positive ions are cations. It is because of their electronic configuration.
This is an outstanding question. On the atomic and molecular scale rotation tends to determine the spherical shape. Molecules do tend to organize in a spherical manner on a large scale as rain drops. However, should the raindrop grow too large as it falls neck instability tends to give it a barbell shape in which it will break into more than one sphere. But besides rotation for planets they tend to "organize" around a center of mass and gravitational forces are at work here. I welcome additional comments on this subject.

Nonpolar molecules tend to dissolve better in other nonpolar molecules due to similar intermolecular forces, while polar molecules dissolve better in other polar molecules. This is because like dissolves like - molecules with similar polarity tend to mix well together. Generally, nonpolar molecules do not dissolve easily in polar solvents.
Polar molecules tend to dissolve in water because water is a polar solvent. Nonpolar molecules are less likely to dissolve in water and usually form separate layers or clusters.
Hydrophobic molecules are another name for non-polar molecules, as they tend to repel or not interact with water due to their lack of partial charges. This property makes them insoluble in water but soluble in non-polar solvents.
Water primarily dissolves polar and ionic molecules due to its ability to form hydrogen bonds with these types of molecules. Ionic compounds such as salts and polar compounds like sugars and alcohols are examples of substances that water can dissolve effectively. Nonpolar molecules like oils and fats do not dissolve well in water due to their lack of polar groups.
The lipid bilayer is made up of nonpolar hydrophobic tails that repel polar molecules, making it difficult for them to pass through. Polar molecules are also unable to dissolve in the hydrophobic environment of the lipid bilayer, further hindering their diffusion across the membrane. This selective barrier allows the cell to control the movement of polar molecules in and out of the cell.
Molecular polarity can affect a molecule's interactions with other molecules. In biological systems, polar molecules tend to interact with water and other polar molecules, while nonpolar molecules tend to interact with other nonpolar molecules. This can influence behaviors such as solubility, membrane permeability, and binding to specific receptors.
Polar molecules like water interact with other polar molecules such as salts, sugars, and some proteins through hydrogen bonding. Nonpolar molecules like oils and fats interact with water through hydrophobic interactions, where they tend to cluster together to minimize contact with water.
Water-fearing molecules are called hydrophobic molecules. They tend to be non-polar and do not interact well with water due to their lack of charge or polarity. As a result, hydrophobic molecules tend to cluster together to minimize contact with water molecules.
Nonpolar substances have lower melting and boiling points than polar substances because their particles are not attracted to each other like polar molecules are. They tend to be gases at room temperature (CO2, CH4, O2, etc). Not much heat is reguired to separate non-polar molecules from one another
Polar Molecules
A polar solute is expected to be soluble in a non-polar solvent. This is because "like dissolves like" – polar molecules tend to dissolve in polar solvents, and non-polar molecules dissolve in non-polar solvents.
Charged and polar molecules dissolve in aqueous solutions due to their ability to interact with the polar water molecules through electrostatic interactions. The partial charges on these molecules allow them to form hydrogen bonds with water molecules, which helps them become evenly dispersed throughout the solution. This enables them to dissolve and form a homogenous mixture with water.
