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

How do you know whether a substance has a greater density than water?
If it sinks in water then it has a higher density than water. If it floats on water surface then its density is less than water.
What are the four elements smaller than uranium?
All the elements with the atomic number under 92 has atomic weights smaller than uranium.
What liquid has a density less than water?
Volatile liquids such as alcohol and ethanol have less density than water. They also evaporate faster than water does.
Compare the density of water and air?
Air's density is less than that of water. Water's density is almost 800 times greater than air.
Does freshwater have a lower density than salt water?
Yes, fresh water has a slightly lower density than salt water.
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.
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?
To solve this question you need to find the sample's density. The formula for density is d=m/v or density = mass divided by volume. You also have to know the density of water, which is 1.so the density of you sample is .2517126 g/cm3because 102 divided by 405.224 (same as 7.403)= .2517126 g/cm3so yes it will float in water because it's density is less than 1 (the density of water).note: because it's less than one doesn't mean it's less dense than all elements. You have to find the less dense element first, and the smaller number will float on the water
How are mass and volume related to the sinking and floating of an object?
An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.
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.
When you compare the density of water or air with another object how can you tell which has the lower or higher density?
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
How do you know whether a substance has a greater density than water?
If it sinks in water then it has a higher density than water. If it floats on water surface then its density is less than water.
