What are the chemical symbols for lithium sodium and potassium?
The element lithium has the symbol Li.The element sodium has the symbol Na (from natrium in Latin and Νάτριο in Greek)The element potassium has the symbol K (from kalium, Latin).
Does lithium and sodium have the same number of protons?
No, lithium and sodium do not have the same number of protons. Lithium has 3 protons, while sodium has 11 protons.
Why does sodium fluoride have a higher melting point than lithium fluoride?
Sodium fluoride has a higher melting point than lithium fluoride because sodium ions are larger and have more electrons than lithium ions, resulting in stronger electrostatic forces between ions in the sodium fluoride lattice. This makes it harder to break the ionic bonds in sodium fluoride, requiring more energy to melt it compared to lithium fluoride.
Why sodium is more reactive the lithum?
Sodium is more reactive than lithium because sodium has an additional electron shell compared to lithium, making it easier for sodium to lose an electron and form a stable electron configuration. This lower ionization energy for sodium results in greater reactivity compared to lithium.
What element atomic number is below sodium and is a metal in the same family as sodium?
The element below sodium with atomic number 11 is lithium. Lithium is a metal in the same alkali metal family as sodium.
