2. Lithium-6 is 4% abundant and lithium-7 is 96% abundant. What is the average mass of lithium?
Lisa [10]

Answer:

Average atomic mass = 6.96 amu.

Explanation:

Abundance of Li-6 = 4%

Abundance of Li-7 = 96%

Atomic mass of Li-6 = 6 amu

Atomic mass of Li-7 = 7 amu

Average atomic mass = ?

Solution:

Average atomic mass  = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass  = (4×6)+(96×7) /100

Average atomic mass =  24 + 672 / 100

Average atomic mass = 696 / 100

Average atomic mass = 6.96 amu.

Hydrogen gas caught fire quickly in the Hindenberg accident. In comparison, neon gas and helium gas are nonreactive. This is why
Phoenix [80]

Answer:

Helium and Neon have similar chemical properties because both of them completely fill the outer shell of their atoms' electrons, so there is nothing to share with other atoms, neither with the same element nor with any other element.

Explanation:  

Helium and Neon are both  noble gases . As elements react, their atoms, by losing, acquiring, or sharing electrons, complete their outer shells. Noble gas atoms already have full outer shells, so there is no tendency for them to lose, gain, or share electrons. There are incomplete outer shells of atoms of group 1 and 7 elements (so they are reactive)

<u>Chemical properties of HELIUM and NEON -: </u>

  • In group 8(or 0) of the periodic table, on the far right side, the Noble Gases are contained. Helium, neon, argon, krypton, xenon and radon are their names.
  • They are extremely colourless and unreactive.
  • They do not form bonds, so they still remain as single (monatomic) atoms.
  • There is very little chemical reactivity in them.

Hence, helium and neon have similar chemical properties as they are the most stable due to having the maximum number of valence electrons their outer shell can hold.

Neon doesn't take part in chemical reaction why give reason​
ankoles [38]
Neon has filled its outer shells, therefore it is very stable and does not need to react with other elements and doesn’t form compounds.
