Would lithium or helium have a higher melting point?
Lithium has a higher melting point than helium. Lithium melts at around 180.5 degrees Celsius, whereas helium melts at a much lower temperature of -272.2 degrees Celsius.
Could lithium react with helium?
In normal conditions, lithium and helium do not react with each other because they are both inert elements. However, under extreme conditions such as in a laboratory setting with high temperatures and pressures, it is possible for lithium to react with helium.
Is helium and lithium a alkali metal?
helium is a noble gas. lithium is an alkali metal.
What are other differences between lithium and helium?
Helium has an atomic mass of 4.- Number of Protons/Electrons: 2- Number of Neutrons: 2Lithium has an atomic mass of 7.- Number of Protons/Electrons: 3- Number of Neutrons: 4Helium has TWO less neutrons than Lithium.
What elements are isoelectronic with Helium Is Li the only one?
H-, Li+, Be2+ ions are isoelectronic with helium
What element is in the same period as helium and has only one valence electron?
The element in the same period as helium that has only one valence electron is lithium. Both helium and lithium are located in Period 1 of the periodic table, with helium in Group 18 (noble gases) and lithium in Group 1 (alkali metals). Lithium has the atomic number 3 and has one electron in its outermost shell, making it highly reactive.
Can you name the primary elements of nature?
Hydrogen, helium, lithium... See a periodic table for the full list.Hydrogen, helium, lithium... See a periodic table for the full list.Hydrogen, helium, lithium... See a periodic table for the full list.Hydrogen, helium, lithium... See a periodic table for the full list.
How does helium-4 behave if thrown?
Helium-4 is a strange super fluid and flow easily.
Are lithium and holmium both elements?
Lithium is an element, however "Holmium" is not you may be mistaking Holmium for Helium though
Why does lithium have a higher first ionisation energy than helium?
Helium has a higher ionization energy than in lithium. Further, helium has the highest first ionization energy in all the elements in the periodic table. Lithium has an electronic configuration of [He]2s1. The outer electron is further out and experiences a lower effective nuclear charge. The 2s electron is further out from the nucleus than the 1s electrons in He. Lithium has an atomic radius of 152pm, whereas helium is calculated at 81pm. The effective nuclear charge on the helium electrons is higher than that acting on the 2s electron in Lithium. Estimates vary a little but roughly for helium it is .69 units. For Lithium the effective nuclear charge is 1.3 due to the "shielding" caused by the inner 1s electrons.
Which three elements have the fewest protons and neutrons?
hydrogen, helium, and lithium
What is the five lightest atoms?
Hydrogen, Helium, Lithium, Beryllium and Boron.
