If the object or matter has a density lower than water does.
No, lead is not buoyant. It is incredibly dense, which makes it very heavy, and not able to float.
As long as any part of the object ... doesn't matter how much ... is below the surface of the water ... doesn't matter how far ... there is buoyant force on it.

Salt Water, because it is makes things more buoyant.
No, the opposite.
it can be more or less buoyant be having more or less mass.i.e. lead will sink in water because the mass is higher and wood will float because it is lighter. the more mass the less buoyant, less mass means more buoyant.
It's full of air that makes it buoyant
Salt makes sea water more buoyant. The Dead Sea has the most salt of any sea in the world, and even people who cannot swim have no problem floating in it.
Buoyant force is based upon the mass of the water displaced. Therefore, two objects will have the same buoyant force if they have the some volumes.
People are buoyant in water because of the upward force exerted on them by the water, called buoyant force. This force is equal to the weight of the water the person displaces. People with lower body fat tend to be less buoyant, while objects with greater density than water will sink.
Because a beachball is filled with air and that makes it buoyant.
The buoyant force, which is the upward force exerted by a fluid on an object immersed in it, makes the rubber duck float in a bathtub. The buoyant force is greater than the weight of the duck, causing it to stay afloat.
