Lithium selenide, Li2Se
The balanced equation for the reaction between lithium and selenium is 2Li + Se -> Li2Se.
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.
The molar mass of lithium selenide (Li2Se) can be calculated by adding the atomic masses of lithium and selenium together. The atomic mass of lithium is approximately 6.94 g/mol, and the atomic mass of selenium is approximately 78.97 g/mol. Therefore, the molar mass of lithium selenide is approximately 163.85 g/mol.
No. Selenium is a nonmetal belonging to oxygen family.
Each hydrogen can form one bond with selenium. Each selenium atom can form two bonds, one with each hydrogen (2 hydrogen atoms total).
The chemical formula for lithium is Li and for selenium it is Se.

Selenium does not typically form a positive ion. It tends to form negative ions (anions) by gaining electrons to achieve a stable electron configuration. Potassium, titanium, and lithium are more likely to form positive ions (cations) by losing electrons.

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)
Selenium can form two bonds with hydrogen.
Selenium form anions.

Yes, selenium is odorless in its pure form. When selenium compounds are formed and interact with other substances, they may produce odors.
