How is air pressure usually measured? A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around the Earth. That air has a weight and presses against everything it touches as gravity pulls it to Earth. Barometers measure this pressure. What time […]

What is electronegativity How does it vary in group and period?
What is electronegativity How does it vary in group and period? The tendency of an atom to attract the shared pair of electrons towards itself is known as electronegativity. Electronegativity increases across a period while it decreases down a group. Atomic radius increases down the group due to addition of new shell. How does electronegativity […]
