The hydrogen bond in polar molecules occurs only in compounds that have hydrogen bonded to N, O, or F.
These very highly electronegative elements create a partial positive charge on the hydrogen.
The H atom is attracted to the partial negative charge on an N, O, or F atom in another molecule.
The hydrogen bond is an attraction but not a true chemical bond such as ionic or covalent bonds. It is much weaker.
However, the hydrogen bond is a strong intermolecular bond.

Match the term to its description.
Amiraneli [1.4K]
I believe that the correct match will be;
Prominences- A
Sunspots - B
Solar flares - C
Convection -D
Prominence is a large, bright feature extending outward from the Sun's surface. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's hot outer atmosphere, called the corona.
Sunspots are darker, cooler areas on the surface of the sun in a region called the protosphere. Solar flares are large eruptions of electromagnetic radiation from the sun lasting from minutes to hours.
