How gravity affects the movement of object? On Earth, gravity pulls all objects to Earth’s center. Gravity acts on all masses equally, even though the effects on both masses may be different because gravity causes all objects to fall at the same constant rate of 9.8 m/s2. An object in free fall means that the […]

Is sodium and magnesium an ionic compound?
Is sodium and magnesium an ionic compound? There is a strong electrostatic force of attraction between these oppositely charged ions – this is called an ionic bond. The slideshow shows ionic bonds being formed in sodium chloride, magnesium oxide and calcium chloride. How do you combine ionic charges? To find the formula of an ionic […]
Why does O 3 not exist?
Why does O 3 not exist? An electrically-neutral oxygen atom gains two electrons to form an oxygen ion with two negative charges. The ion would thus be highly unstable and potentially readily lose that outermost electron and return to O3− as the ten inner shell electrons seek to get rid of the additional electron. Why […]
