In water molecules there are 2 atoms of hydrogen of and 1 atom of oxygen present. each hydrogen atom shares 1 electron with the oxygen atom. So the total number of electrons shared with oxygen are 2,total no. of electrons shared by hydrogen is 2 and the total no. of electrons shared by each hydrogen atom is 1.
Electrons found in the outermost energy level of an atom are called valence electrons. These electrons are involved in forming chemical bonds with other atoms, which determines the atom's reactivity and behavior in chemical reactions. The number of valence electrons an atom has contributes to its position in the periodic table and helps predict its chemical properties.
The outermost electrons of an atom, also known as valence electrons, have higher energy levels compared to the inner electrons. Valence electrons are involved in chemical bonding and interactions with other atoms, while inner electrons are more tightly bound to the nucleus and have lower energy levels.
The outermost energy level configuration for Calcium is 4s2, meaning it has two electrons in the 4s orbital.
Outer energy level electrons, or valence electron.
Core electrons have lower energy levels than valence electrons. Core electrons are closer to the nucleus and are more tightly bound, while valence electrons are in the outermost energy level and have higher energy due to being farther from the nucleus.
An oxygen atom has 6 electrons in its outermost energy level. In a water molecule, each hydrogen atom can share one electron with the oxygen atom, forming a covalent bond. This results in the oxygen atom having a total of 8 electrons in its outermost energy level.

Eight. Oxygen has 6 electrons and shares two more with the hydrogen atoms in covalent bonds
counting the shared electrons, 8.
In a water molecule, oxygen shares electrons with hydrogen atoms to form covalent bonds. Oxygen has 6 electrons in its outermost energy level, while hydrogen has 1 electron in its outermost energy level. Oxygen shares one electron with each of the two hydrogen atoms, forming two covalent bonds.
