What else can I help you with?
The first element with an electron in the second energy level?
The first element with an electron in the second energy level is lithium. Lithium has three electrons, with two in the first energy level and one in the second energy level.
Is lithium nitrate a strong or weak electrolyte?
Lithium nitrate is a strong electrolyte, meaning it dissociates completely into ions when dissolved in water, resulting in a solution that conducts electricity well.
How many energy levels does lithium have?
there are two protons in the first level and one proton in the second level of Lithium
How does the energy of the 2s subshell compare to the energy of the 2p subshell in a lithium atom?
In a lithium atom, the energy of the 2s subshell is lower than the energy of the 2p subshell.
How many electrons in the first energy level of lithium?
Lithium has a total of 3 electrons. The first energy level of an atom can hold a maximum of 2 electrons, so the first energy level of lithium will have 2 electrons.
Does lithium conduct electric?
Yes, lithium is an alkali metal and it conducts electricity. Its symbol is Li and its atomic number is 3.

Which has high ionisation energy lithium or lithium plus?
lithium plus. removing electron from something that is positive is much harder.
How many electrons in the first energy level of lithium?
Lithium has a total of 3 electrons. The first energy level of an atom can hold a maximum of 2 electrons, so the first energy level of lithium will have 2 electrons.
Why is lots of energy required to separate lithium and oxygen in lithiumoxide?
Separating lithium and oxygen in lithium oxide requires a lot of energy because it involves breaking strong chemical bonds between lithium and oxygen atoms. It takes significant energy to overcome the attractive forces holding these atoms together in a stable compound like lithium oxide.
What energy level are the valence electrons located in lithium?
2nd energy level, the electron arrangement is 2,1 at ground state
Which atom lithium or cesium needs more energy to become an ion?
Cesium needs more energy to become an ion than lithium because cesium has a higher ionization energy due to its larger atomic size and greater distance of valence electrons from the nucleus. This makes it more difficult to remove electrons from cesium compared to lithium.
What material conducts thermal energy poorly is a?
thermal insulator
What does lithium and chlorine make?
Lithium and chlorine react to form lithium chloride, a white crystalline salt. The reaction between lithium and chlorine is highly exothermic and releases a large amount of energy.
