group 1 metals have only one electron in the outermost shell.it gives out electrons easily as it is highly electropositive and called as highly reactive metals..water has the polarity..due to this property the OH ions in water becomes slightly electro-negative and attracts the electro positive metal thus forming hydroxides..and also due to this reaction hydrogen gas is formed along with the formation of hydroxides..
That element would be in the Alkali Metals (group one)
The element in group 1 period 3 is sodium. Sodium has an atomic number of 11 and is a highly reactive metal.
It is hydrogen. This element is the only one in its group because it is extremely unique and shares none of the properties of other gases.
A specific gravity less than 1 allows a chemical to float in water. This means the chemical is less dense than water and so it will float on the water's surface instead of sinking.
A chemical will float in water if its density is less than the density of water (approximately 1 g/cm3). This can be determined by comparing the densities of the chemical and water. If the chemical's density is less than water, it will float; if it is greater, it will sink.
molecules make an object float the airs density has gases that react to substance and then change phase an element has only 1 kind of atom and that atom gets
For something to be able to float on water, it requires a density lower than water. Water at room temperature has a density of 1 kg / L or 1000 g / dm3Atomic number 43 is the element Technetium. At room temperature Tc has a density of 11 g / dm3.So yes, it will float on water.
No, a 1 by 5 kg object will not float on water because its density is greater than that of water, causing it to sink. Objects float on water when their density is less than that of water.
The reaction is stopped when no hydrogen is released.
If you mean in the group {1, -1, i, -i, j, -j, k, -k}, the identity element is 1.
If we look at the periodic table, we can see that the first element in Group I is Hydrogen.
lithium is the third element. It is placed in group-1
The second element in group 1 is beryllium, with an atomic number of 4.
any substance (colored or not) with a density less than 1 will float on water
1 kg of water will float in ethanol because ethanol is less dense than water.
That element would be in the Alkali Metals (group one)
element K, or potassium
