Most don't, but a few do. Na and K come immediately to mind ie the Alkali Metals.

What two elements can float on water?
Two elements that can float on water are lithium and potassium. These elements have a lower density than water, which allows them to float on its surface.
How do you know whether a substance has a greater density than water?
You can compare the density of the substance to the density of water, which is 1 g/cm^3. If the substance has a density greater than 1 g/cm^3, then it is denser than water.
Can Antimony float in water?
No, antimony sinks in water because its density is greater than that of water.
Is the density of rubber stopper is denser than the density of water?
No, the density of a rubber stopper is less than the density of water. Rubber has a lower density compared to water, so a rubber stopper would float on water.
What are the four elements smaller than uranium?
The four elements smaller than uranium on the periodic table are neptunium, plutonium, americium, and curium. These elements have atomic numbers 93, 94, 95, and 96, respectively.
Would white beans float on water?
Because they have a smaller density than water
Is density of 2 mL of water smaller of larger than 1 mL of water?
The density of any substance remains the sameirrespective of its volume.
Which of the jovian planets has a density smaller than water?
I'm pretty sure Saturn would float in water.
Why do ships float when stones sink?
Things that float have a smaller density than water and things that sink have a larger density than water. Because a stone is heavy for its size it sinks but although a ship is heavier its mass is spread out over a larger area so its density is smaller and therefore it floats.
Does lead float or sink in water?
Lead sinks in water due to its high density, which is greater than the density of water. This causes it to displace a smaller volume of water compared to its own volume, resulting in it sinking.
If you are submerged in a liquid denser than water what will happen to the pressure?
The pressure will get higher quicker than in water because there is a different density between the liquids, and because there is a higher density, the liquid will be heavier and would push on you more than the smaller density of water. if you would submerge deep in that liquid, you will explode at a lower distance from the surface than in water.
What is in an egg that makes it floats?
Increasing the air cell (in time, for unfresh eggs) of the eggs lead to floating in water, because the density of the egg become smaller than the density of water.
Why does a kilogram of lead occupy a much smaller volume than a kilogram of water?
lead has much higher density
A 7.40 cm3 sample of mercury has a mass of 102 g will it float in water?
No, the sample of mercury will sink in water because the density of mercury (13.6 g/cm3) is higher than the density of water (1 g/cm3), indicating that mercury is denser than water and will not float.
What two elements can float on water?
Two elements that can float on water are lithium and potassium. These elements have a lower density than water, which allows them to float on its surface.
Why is density needed to know whether a substance will float or sink in water?
It's actually pretty easy. If the density of the substance is higher than the density of water, the object will sink. If the density of the substance is lower than the density of water, the object will float. Be aware though that various substances may have dissolved into the water, thus changing its density. For example, seawater has a different density than fresh water.
How are mass and volume related to the sinking and floating of an object?
Mass and volume are related to the sinking and floating of an object through their density. An object will sink if its density is greater than the density of the fluid it is placed in, and will float if its density is less than the density of the fluid. The relationship can be expressed as density = mass/volume.
