Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Hydrogen atoms are slightly ____
A
positive
B
negative
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The hydrogen atom has a slightly positively charge because it cannot hold as tightly to the negative electron bones. Covalent molecules with this type of uneven charge distribution are polar. Molecules with polar covalent bonds have a positive and negative side.

Detailed explanation-2: -Complete answer:-Hydrogen is a positively charged ion. The first element in the periodic table is hydrogen because the number of the electron in hydrogen is 1.

Detailed explanation-3: -Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H2O molecule adopts a slightly different charge. The area around the oxygen is somewhat negative compared to the opposite, hydrogen-containing end of the molecule, which is slightly positive.

Detailed explanation-4: -In a water molecule (H2O), the oxygen nucleus with +8 charges attracts electrons better than the hydrogen nucleus with its +1 charge. Hence, the oxygen atom is partially negatively charged and the hydrogen atom is partially positively charged.

Detailed explanation-5: -The two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds. While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water’s properties of attraction.
