What alkali metal has two energy levels?
Lithium is the alkali metal that has two energy levels in its electron configuration. Its electron configuration is [He] 2s¹.
When hydrogen reacts with the active metals it forms a chemical bond by?
gaining an electron
Which element is a metal with an outermost electron configuration of 6s2?
The element with an outermost electron configuration of 6s2 is Barium (Ba). It is classified as an alkaline earth metal on the periodic table.
What is it called when a Halogen reacts with a metal?
When a halogen reacts with a metal, it is known as a halogenation reaction. During this reaction, the halogen gains an electron to form a negatively charged ion while the metal loses an electron to form a positively charged ion, leading to the formation of an ionic compound.
What alkaline earth metal has the largest electron affinity?
Barium has the largest electron affinity among the alkaline earth metals.
Which ion in manganese nitrate is responsible the compounds colour?
Manganese. Transition metal ions exhibit electron transitions between their electron orbitals which absorb light of certain wavelengths, making the compound coloured.
How can hydrogen act ad a metal and a nonmetal?
Hydrogen has 1 electron. It can easily gain or lose electron to form metal or non metal
Which alkaline earth metal is part of the reaction of photosynthesis?
Magnesium is the alkaline earth metal that is part of the reaction process of photosynthesis.
When an alkali metal reacted with a non metal what happens to the loan outer shell electron?
The electron outside the shell donate its electron to the one inside the shell
Which alkaline earth metal is part of the reaction process of photosynthesis?
Magnesium is the alkaline earth metal that is part of the reaction process of photosynthesis.
What alkali metal requires 4 electron shells?
Cesium (Cs) is the alkali metal that requires 4 electron shells as it has the electron configuration [Xe] 6s1.
Why is alkalai metals in the periodic table very reactive?
Alkali metals are very reactive.They have free electron in their outermost shell which is responsible for high reactions.For example : Lithium metal.
Does metal refining depend on photosynthesis?
yes
What alkali metal has two energy levels?
Lithium is the alkali metal that has two energy levels in its electron configuration. Its electron configuration is [He] 2s¹.
Is flouride a metal or non metal?
Fluoride is an ion formed by the nonmetal fluorine.
Why does the metal's radius get smaller and the nonmetal's radius get larger during an ionic bond?
Because the metal loses an electron (making it smaller) and the non metal gains that electron, making it larger.
What happens to the valence electron in an alkali metal when it combines with a halogen gas?
This electron is lost.
