A sodium atom forms NA+1 ion by losing two electrons
Answer:
A molecule is tetrahedral if the central atom has four bonds and no lone pairs.
Explanation:
A typical example is a molecule of methane (see image).
The electron pairs in the bonds repel the electrons in the other bonds, so they all try to get as far from each other as possible.
They can do this if the bonds point to the corners of a tetrahedron, with bond angles of 109.5°.
Answer:
The type of bond between the Oxygen atom and the hydrogen is Covalent
this is because the 2 electrons are being shared by both hydrogen and oxygen
The type of bond this molecule makes as a whole is called a Hydrogen Bond
A hydrogen bond is formed because of the partial +ve and -ve charge in a molecule
The cause of the partial +ve and -ve charge is the comparatively high electronegativity of oxygen which makes the electron get attracted towards the oxygen atom while the hydrogens try to maintain the maximum distance from the lone pairs due to repulsion
