Four electrons reduce one molecule of oxygen gas to form water
There are 22 electrons in one molecule of CO2.
One oxygen atom shares electrons with two hydrogen atoms to create a water molecule.
Water molecules are composed of two atoms of hydrogen and one atom of oxygen. The hydrogen atoms each bring an electron to the reaction, and the oxygen atom brings eight. The resulting molecule has two plus eight electrons, or ten electrons in it.
One.
None; the oxygen has 2 missing "spaces" for electrons. The two hydrogens have 1 missing "space" for an electron each. Through sharing, all of the atoms fulfill the octet rule. (8 e- in outermost orbital)
One atom of Oxygen and two atoms of Hydrogen combine to form a water molecule by the shearing electrons, water has the chemical formula H2O.
Paramagnetic molecules have unpaired electrons, while diamagnetic molecules have all paired electrons. One can determine if a molecule is paramagnetic or diamagnetic by examining its electron configuration and counting the number of unpaired electrons. If there are unpaired electrons, the molecule is paramagnetic; if all electrons are paired, the molecule is diamagnetic.
Water molecule is a polar molecule because it has a slightly negative charge on the oxygen atom and slightly positive charges on the hydrogen atoms. This unequal distribution of charge creates a positive and negative pole in the molecule, making it polar.
A molecule shouldn't have valence electrons left.
No, the atoms within a given water molecule are covalently bonded to each other, but the molecules are not covalently bonded to other water molecules. Instead they have what is called a coordinate covalent bond. In a covalent bond, atoms share electrons. In a coordinate covalent bond, there is no sharing of electrons but there are regions of electric charge (water molecules have a positive and a negative end to them due to the pattern in which the electrons are distributed) and that causes an electrostatic attraction.
Water is considered a polar molecule because it has a slightly positive charge on one side and a slightly negative charge on the other side, due to the uneven distribution of electrons between the oxygen and hydrogen atoms in the molecule.
