How many protons and electrons dose H plus have?
H+ has 1 proton and 0 electrons.Normal hydrogen has 1 proton and 1 electron. The number of protons always remains the same. The negative electron and the positive proton balance out the charge so that normal elemental hydrogen is neutral.H+ is the oxidized form of hydrogen. Its electron was taken away, so now it's left with 1 proton and 0 electrons, making its charge positive.H- is the reduced form of hydrogen. It has gained an electron, so now it has 1 positive proton and 2 negative electrons, making the charge equal to negative 1.
Are oxygen atoms in water molecules negatively charged?
Yes, each oxygen atom in a water molecule carries a slight negative charge due to differences in electronegativity between oxygen and hydrogen. This partial negative charge on the oxygen atoms results in the overall polar nature of water molecules.
Dose a negative number plus a negative number equal a positive number?
No. The sum of two negative numbers will always be a negative number. If, however, you multiply the numbers, their product will be positive.
What dose integers mean?
