When an atom or molecule accepts or looses an electron or electrons it gets either negative charge (when electrons gained) or a positive charge (when looses electron). The negative ion is called Anion and positve ion is called the Cation. An Ion can be Atomic or Polyatomic.
Example:
Sodium when looses one electron forms a cation i.e. Na⁺
Chlorine when gains one electron forms an Anion i.e. Cl⁻
Result:
<span>A negative ion (Anion) differ from an uncharged atom of the same element in the number of electrons. An anion contains more electrons than its corresponding Neutral Element.</span>
The answer is; liquid phase
The characteristics described in the question are those of a liquid. The forces between liquid particles are weaker than the forces between solid particles because the particles are further apart. The particles are not held in a fixed position in the structure hence it can flow and take the shape of the container in which it is in.
<u>Answer: </u>The correct answer is Option A.
<u>Explanation:</u>
The molecule given in the question is HCl which forms a polar covalent bond.
A polar bond is defined as the bond present between two elements with different electronegativity value. The element which has higher electronegativity value, attracts the shared pair of electrons towards itself and forms a dipole. A polar molecule is dissolved more in a polar substance than in non-polar substance.
In the given compound, the electronegativity of chlorine is more than hydrogen and attracts the shared pair of electron more towards itself and hence is a polar molecule.
A non-polar bond is defined as the bond which is formed between the elements having same electronegativity value. No dipole is created in these type of bonds. Here, the electrons are shared equally.
From the above information, the correct answer is Option A.
Answer:
Hey mate.....
Explanation:
This is ur answer......
<em>While sunlight is the energy source, the greatest force propelling the water cycle is gravity. Gravity is the force of attraction between two objects, and Earth's gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water.</em>

Electron
Atoms, compounds, and molecules undergo chemical reactions to form new substances. In general, reactions proceed to produce products which are have more stability.
These chemical reactions are possible because of the ability of substances to form chemical bonds with other substances. These formation of bonds are primarily attributed to electronic interactions (i.e. the valence or outer electrons of the atoms). of substances.
Atoms are able to form new substances by gaining, losing, or sharing electrons with other atoms.
