The 2 metal which exist in gases state are metallic hydrogen and the two allotropes of oxygen which are dioxygen and ozone.
No. Magnesium is a group 2 metal.,
Iron has oxidation state of -2, in the Tetracarbonyl Ferrate ion
The oxidation state of oxygen in alkaline earth metal oxides is -2. Alkaline earth metals always have a +2 oxidation state, which means oxygen has to have a -2 oxidation state to balance the charges in the compound.
The Sun is primarily composed of hydrogen (about 74%) and helium (about 24%). Trace amounts of other elements, including oxygen, carbon, neon, and iron, make up the remaining 2%. These gases exist in a plasma state due to the extremely high temperatures and pressures in the Sun's core.
There are 3 groups of non-metals in which they are : Halogens, Noble Gases and Other nonmetals
There are no such metals whose common oxidation state is -2
Five elements that exist as gases at room temperature are hydrogen, oxygen, nitrogen, fluorine, and chlorine. Five compounds that exist as gases at room temperature are carbon dioxide, ammonia, methane, hydrogen chloride, and sulfur dioxide.
Yes, iron is a transition metal that can have multiple oxidation states, including +2 and +3. These different oxidation states enable iron to participate in a wide range of chemical reactions and form various compounds.
No, Pb is not a transition metal and it has 2 oxidation states
No. Barium is an alkaline earth metal (or group 2 element). Noble gases are group 18 elements.
One example of a metal with a negative oxidation state in its compound is iron in the compound FeH2, where iron has an oxidation state of -2. Another example is copper in the compound Cu2S, where copper has an oxidation state of -1.
Zinc commonly exists in compounds in the +2 oxidation state only, and as a metal with an oxidation state of 0.0, 1 and 2 oxidation states
