All of them has one electron in their outer shell.
No. Hydrogen an oxygen are both elements. Elements do not contain other elements.
Hydrogen is placed with the elements in group 1A (1) because it has one electron in its outermost shell, similar to other group 1A elements like lithium, sodium, and potassium. However, hydrogen is unique as it is not a metal like the other elements in this group, exhibiting properties of both metals and nonmetals.
Hydrogen can react with practically all other elements.
None. Hydrogen, oxygen, and carbon are all elements. Elements do not contain other elements.
No. Hydrogen and helium are separate elements. Elements do not contain other elements. But an element can give off or take electron from other elements.
The moon's composition is similar to that of Earth's crust, with elements such as oxygen, silicon, magnesium, iron, calcium, and aluminum. There are also traces of other elements like titanium, hydrogen, and potassium.
Hydrogen, like other elements are vegan.
Hydrogen and oxygen are already elements. Elements do not contain other elements.
Chlorine ,Bromine and Iodine have same chemical properties as Fluorine.
For the most part at the moment our Sun is made up of hydrogen fusing into helium, they account for 74.9% and 23.8% of the suns mass other elements known as metals account for less than 2% of the mass. The most abundant metals are oxygen (roughly 1%), carbon (0.3%), neon (0.2%), and iron (0.2%). When the sun runs out of hyrdogen to fuse it will start to convert Helium in to Carbon, at this point life on earth will not be viable.
