Oxygen is more electronegative (not electromagnetic !).
No. The oxygen atom in a water molecule has a partial negative charge, and so it would not readily interact with Cl-, another negatively charged species.
Shared electrons in a water molecule are most likely found in the covalent bonds between the oxygen and hydrogen atoms. In water, the oxygen atom shares electrons with the hydrogen atoms to form two polar covalent bonds.
The central atom in a molecule is typically the one that is most electronegative.
Atom
Water is a coumpound made up of two elements, hydrogen and oxygen, which makes the most basic unit of water a molecule, not an atom, which is the most basic form of an elements, so no elements contain water.
Yes, that molecule is water (H2O). It is the most abundant compound on Earth and essential for life.
Hydrogen bonding.
A proton is smaller than a molecule, which is a group of atoms bonded together. The nucleus is smaller than both a molecule and an atom, as it is the central part of an atom where most of its mass is concentrated.
Hydrogen is the lightest of all elements, having atoms that are only a fraction of the mass of all other elements. For example, an oxygen atom has about 16 times the mass of a hydrogen atom. So while a water molecule contains 2 hydrogen atoms and 1 oxygen atom (and water makes up most of the human body), the single oxygen atom accounts for most of the mass of the molecule.
The electromagnetic force is the most important force inside an atom. It governs the interactions between charged particles such as protons and electrons, holding the atom together.
You have 60 % of water in your body. So the most prevalent molecule is H2O or water molecule in your body.
From H and O, oxygen is the most electronegative, so that the negative side of the H-O-H 'triangle' with O in top.
