May 24, 2024 · In a water molecule (not an ion - just the molecule) the protons and electrons are matched in number. The hydrogen has 1 proton each. Oxygen has 8 protons. Since water is H2O, you have 2x1 + 8 ...

Oct 29, 2015 · You can determine that by using the molar mass in "g/mol" of the water molecule and converting so that you get the absolute mass in "g". The molar mass is "MM"_("H"_2"O")" = 18.015 g/mol". If you don't remember that, you can also look it up on Wikipedia, or refer to a periodic table and add up the molar masses of two hydrogen atoms and one ...

May 21, 2024 · Water (H2O) has both atoms and molecules in it. H20 is a molecule, but 'H' and 'O' are atoms. The '2' indicates how many atoms of the element before it there are. Lots of these molecules of H2O ...

May 16, 2018 · Water #(H_2O)# is a polar molecule because the electrons of the hydrogen atoms get "pulled" towards the electrons of the oxygen atom. This makes a region of positive charge on the hydrogen atoms and the negative charge on the other end of the molecule, which is the oxygen atom. Have a look here:![) This also allows for hydrogen bonding.

Jun 21, 2018 · The slightly positive hydrogen atoms of one water molecule will thus be attracted to the slightly negative oxygen atoms of another water molecule (Coulombic attraction). Here's a diagram of that attraction: However, oxygen is not the only element that is capable of doing this and hydrogen bonding is exhibited in many other molecules.

Nov 8, 2014 · There are three dipoles in a water molecule. Since O is more electronegative than H, the O-H bond is polar. The negative end is at the O atom, and the positive end is at the H atom. There are two O-H bonds, so there are two bond dipoles. These two bond dipoles are vectors. They combine to form a vector sum with the resultant pointing from the mid-point between the H atoms to the O atom. This ...

Nov 3, 2016 · The molecular formula for water is H_2O, meaning there are 2 hydrogen atoms and one oxygen atom. I found this by adding the subscripts. 2 is the subscript on hydrogen, and 1 is the subscript on oxygen, so 2 + 1 = 3 atoms total. For example, to count the number of atoms in one molecule of glucose, C_6H_12O_6, add the subscripts, so 6+12+6 is 24 ...

Jun 17, 2024 · Yes, water is a polar molecule because it has a slight negative charge on the oxygen atom and a slight positive charge on the hydrogen atoms due to differences in electronegativity.

May 26, 2024 · A water molecule has two types of bonds: covalent bonds between the oxygen atom and the hydrogen atoms within the molecule, and hydrogen bonds between water molecules. The covalent bonds hold the ...

May 23, 2024 · A water molecule has two types of bonds: covalent bonds between the oxygen atom and the hydrogen atoms within the molecule, and hydrogen bonds between water molecules. The covalent bonds hold the ...
