Question

Difference between hydrogen and lithium atom

Answer 1

Answer:

There is one strong similarity, and there are many differences.

The similarity: each can easily yield one electron to enter combination.

Some differences:

· Hydrogen can also easily gain one electron to form compounds.

· Hydrogen bonds covalently; lithium bonds ionically.

· Hydrogen has a single proton for a nucleus, and usually no neutrons.  

· Lithium has three protons and four (usually) or three (sometimes) neutrons, in its stable isotopes.

· Hydrogen is a gas of diatomic molecules at ordinary temperatures (and rather lower temperatures too); lithium is a solid below 180.50 °C.

· Hydrogen is usually counted as a nonmetal; lithium is highly metallic.

· Hydrogen is colorless; lithium is silvery and opaque.

· Hydrogen is diamagnetic; lithium is paramagnetic.
