Picture the water molecule as a Mickey Mouse hat. (This from another post, and a big thanks to that author for the visual.) The two "ears" are the hydrogen atoms, and the bigger round "hat" part is the oxygen atom. The hydrogen atoms will (mostly) have their electrons between themselves and the oxygen atom. That leaves the hydrogen nuclei (each a proton, and rarely a neutron or, even rarer, two) sticking out in space exposing their positive backsides. The oxygen atom will be a touch negative, and that is the end with the minus charge. Picturing the mickey mouse hat on an individual standing in front of the observer, the positive end of the molecule would be above and between the ears, and the negative end of the molecule would be at the hat-wearer's chin.

∙ 13y agoThe Na+/K+ pump is found in the membranes of many types of cells. It plays a very important role in never cell membranes. 3 positive ions (Na+) are pumped out of the cell for every 2 positive ions (K+) pumped into the cell. This means that there are more positive charges leaving the cell than entering it. As a result, the positive charge builds up outside the cell compared to inside the cell.
The difference in charge between the outside and the inside of the cell allows nerve cells to generate electrical impulses, which lead to nerve impulses.

What struggle produces the partial negative and partial positive charges on a water molecule?
The water molecule has a partial negative and partial positive charge because it is a polar molecule. Electrostatic attraction between the partial negative and partial positive molecules gives the water molecule its partial charge.
Does dissociation of salts keep salt molecules stable in water?
When sodium chloride is dissolved in water, a process called solvation occurs. Water is a polar in nature and it is a polar solvent. The water molecule has a positive end and a negative end . The positive part of the water molecule is attracted to the negative part of the sodium chloride, the chloride ion. The negative part of the water is attracted to the positive part of the sodium chloride, the sodium ion. Thus, the sodium chloride dissociates, or breaks apart in water
Why are ironic substances soluble in water a polar solvent?
Water molecules are polar in character, they possess a dipole. The positive part of the water molecule is attracted to the negative ion in the ionic substance, and the negative part of the water molecule to the positive ion. The resulting release of energy encourages the process of dissolving. The solubility of ionic substances is variable and depends on other properties of the constituent elements.
What causes water to be more polar molecule?
Because of the way the hydrogens bond to the oxygen in water, the molecular geometry is a bent or angular shape, and the oxygen has 2 lone pairs of electrons. This makes the oxygen part of the water molecule rather negative relative to the hydrogen part of the molecule, which is rather positive. Thus, there is a separation of charge, and this is what makes the water molecule so polar.
What characteristic of water helps it cause a mineral to dissolve?
Water is a polar molecule meaning the oxygen part is negative the hydrogen is positive, so in an ionic compound the negative ion get attracted to the hydrogen and the positive ion to the oxygen.
Explain how a water molecule can be attracted to both a positive ion and a negative ion when dissolving an ionic compound?
The shape and charge distribution in a water molecule cause it to have a permanent dipole moment, which consist of a positive electric charge and a negative charge separated by a distance in space. Therefore, the part of a water molecule that corresponds to the negative charge of its dipole moment is attracted to positive ions, and the part of a water molecule that corresponds to the positive charge of its dipole moment is attracted to negative ions.
What explains the solubility of ionic substances in water?
Ionic substances dissolve in water because of the attraction exerted between positive ions and the negatively charged oxygen part of the water molecule, and also between negative ions and the positively charged hydrogen part of the water molecule.
Why does water dissolve substances?
Water is a universal solvent because substances get dissolve in water easily. It is due to the polarity of each water molecule. The hydrogen has a positive charge, thus attracting the negative part of an ionic compound, while the oxygen has a negative charge and thus attracts the positive part of an ionic compound.
The hydrogen side of a water molecule is?
The hydrogen side of a water molecule has a slight positive charge.
What struggle produces the partial negative and partial positive charges on a water molecule?
The water molecule has a partial negative and partial positive charge because it is a polar molecule. Electrostatic attraction between the partial negative and partial positive molecules gives the water molecule its partial charge.
Why is a water molecule considered to be a polar molecule?
A water molecule is considered a polar molecule because of its shape. That is, its poles contain opposing charges, the positive and negative charge.
Why does each molecule of water acts as a tiny magnet?
Water molecules are polar, which means that one part of the molecule has a positive charge and the other has a negative charge just like the polar ends of a magnet.

Water dissolves many ionic and molecular compounds because of its what?
Water is a highly polar molecule which means that one side of the molecule is slightly positive and the other is slightly negative. This means that water molecules are attracted and can form weak bonds with molecules that also have positive sides and negative sides (polar molecules). Basically, the positive side of the water molecule is attracted to the negative side of the polar molecule and the negative side of the water molecule is attracted to the positive side of the polar molecule. Is this way the water is able to surround and separate the polar molecules. The story is much the same for an ionic compound which contains a mixture of positive and negative ions. The positive side of the water molecules surround the negative ions and the negative side of the water molecules surround the positive ions.
What kind off molecule has a positive end and a negative end?
A polar molecule such as water
