What is the Chemical formula for lithium and selenium?
The chemical formula for lithium is Li and for selenium it is Se.
What would react with water as lithium sodium and potassium?
Lithium, sodium, and potassium react vigorously with water to form hydroxides and release hydrogen gas. The reactivity increases as you go down the group from lithium to potassium, with potassium being the most reactive.
What happens when potassium hydroxide mixed with lithium?
When potassium hydroxide is mixed with lithium, a single displacement reaction occurs. Lithium will replace potassium in the potassium hydroxide solution, resulting in the formation of lithium hydroxide and potassium metal as products. The reaction is represented by the following chemical equation: 2Li(s) + 2KOH(aq) -> 2LiOH(aq) + 2K(s).
Which elements have the same properties of sodium?
The are the other alkali metals: lithium, potassium, rubidium, caesium.
How many outermost electrons do lithium and potassium have?
Both lithium and potassium are in Group I of the Periodic Table, so they both have one valence electron.
What is the Chemical formula for lithium and selenium?
The chemical formula for lithium is Li and for selenium it is Se.
Is selenium a akali metal?
No. Selenium is a nonmetal belonging to oxygen family.
What does lithium and selenium form?
Lithium selenide, Li2Se
Name a metal on the peridoic table?
Tungsten. Mercury. Tin. Gold. Lithium. Potassium. Calcium. Sodium. Titanium. Chromium.....................................................
What is the balanced equation of lithium and selenium?
The balanced equation for the reaction between lithium and selenium is 2Li + Se -> Li2Se.
What is the element with the Neutron number 44.96?
You can't have 0.946 of a neutron. You've either got a whole neutron or you don't. So the answer is "there is no element with a neutron number of 3.946".The average number of neutrons in lithium is close to that. Somewhere between about 7.5% and 3.75% of lithium atoms have 3 neutrons; the rest have 4. That nicely brackets an average of 3.946 (which would correspond to 5.4% 6Li)
What is the chemical formula for the compound formed Between Lithium and selenium?
The compound formed between lithium and selenium would have the chemical formula Li2Se. This is because lithium is in Group 1 of the periodic table and has a +1 charge, while selenium is in Group 16 and has a -2 charge.
What are three metals that are elements?
Lithium, Sodium, Magnesium, Aluminum, Potassium, Calcium, Scandium, Titanium, Vanadium, Chromium, Iron, Cobalt, Nickel, Copper, Zinc etc
What atom loses its electron easily is it carbon potassium lithium or hydrogen?
Potassium. This can be seen by the potassium setting itself on fire in water. Can lithium, carbon or hydrogen do that?
Why is lithium harder than potassium in structure and bonding?
It is because Lithium has the smallest atomic radius of them all, because it has only two shells of electrons.So the small lithium nuclei, with their one positive charge each are more easily held together by the delocalised elextron cloud than the much larger sodium or potassium ions that still only have one positive charge each.potassium is more reactive owing to the loosely bound valence electron owing to a relatively more "electron shielding" effect.The valence electron is partially shielded from the attractive force of the nucleus by the inner electrons.Although lithium and potassium have one valence electron.The difference in hardness between lithium and potassium is primarily due to their atomic structures and bonding. Lithium has a smaller atomic radius and stronger metallic bonding compared to potassium. This makes lithium atoms more tightly packed and bonded, resulting in a harder substance compared to potassium.

What happens when lithium reacts with potassium hydroxide?
There will be no reaction between the lithium and the potassium hydroxide. However, since the potassium hydroxide is in solution, the lithium will still react with the water to form lithium hydroxide and hydrogen gas. 2Li + H2O --> H2 + LiOH.
