Lithium, sodium, and potassium all float on water.
Sodium and lithium both react with the water to give off hydrogen gas - they look a bit like fizzies when they do it. They can give off enough heat to light the gas, so they burn as they float around if there is enough oxygen to support a flame. I imagine potassium would act the same way, but I have never seen it personally.
Beryllium, the lightest element in the alkaline earth group, is more dense that water, and would not float.
No solid chunk of metal will float, but all metals will float if formed into a hollow shell that overall have less density than water.
Iron, copper, gold, aluminum, brass, titanium, zinc. I believe all metals are heavier than water but some thin sheets of metal such as Aluminum can float due to its bouyancy. You can probably cut anything into small enough size such that it would float. BTW, I can make steel float----in liquid lead.
If you're floating metal on water, there are only a couple or three metals that have a density so low that they'll float on water. Those metals are lithium, potassium and sodium. Any one of these will float on water, and they are listed in order of increasing density with sodium just a bit less dense than water. Note that all of these metals will react violently with water, so we're setting this issue aside here. Be clear about that.
What sediment float in the water
an egg can float in salt water.
no an egg does not float in regular water.
The alkaline metals react with water, and Lithium and Sodium float on the water whilst reacting.
rocks, metals ect.
Such metals are Sodium and Potassium (and all the alkali metals).
It will sink in water, but it will float in mercury. Depends on what the liquid is.
If the proposal is to float the metal on water, most metals won't float. That's because most metals are more dense than water and will sink. Note that this proposition sets aside any reaction that might occur between the metal and water. This is because there are some metals that react with water, and some react violently. See the link below to the related question about the metals that will float on water. There aren't many of them. If the metal you are considering isn't on the list of metals that willfloat on water, then it won't.
Metals have a high density and they feel heavy so as magnesium is a metal it will not float in water due to the tight compression on the molecules packed in it.
Hardness, ability to float or sink in water and so on.
There are several ways.It could be made of one of the metals that actually do float on water: lithium, sodium, and potassiumIt could be formed into a shape that spreads the weight around so much that the water will support it, such as a boat.

it depends most metals ill sink except for titanium which is less dense than water

For something to float, it must displace the same amount of water as it weighs. Answer:To float in water, a solid metal object must be lighter than the water equivalent to its volume. This would make lithium (at S.G. 0.53) the only metal that would float in water.Objects which are hollow and made of metal float because the contained volume of the object divided by the weight of the object is less than 1 gm/cm3, the density of water. Solid metal objects can float in liquids which have a density greater than they exhbit thesmelves. As an example, almost all metals will float in mercury
