107. The lightest noble gases, such as helium and neon, are completely inert—they do not form any chemical compounds whatsoever.

The heavier noble gases, in contrast, do form a limited number of compounds. Explain this difference in terms of trends in fundamental periodic properties.

Explanation:

Noble gases are group O elements and their atomic structure ensures that they are stable. All their orbitals are completely filled with electrons therefore they do not undergo reactions with other elements.

  • Heavier noble gases are able to form a range of compounds due their sizes.
  • Elements form compounds by exchanging or sharing of their outermost shell electrons called the valence electron.
  • Every atom has specific energy required to remove electrons from them. The energy is known as the ionization energy.
  • In bigger atoms which have large radius, the outermost electrons have low ionization energy which makes them easy to remove.
  • The ionization energy depends on the nuclear charge, the more the charge the higher the ionization energy. Down a group the nuclear charge and ionization decreases.
  • As we go down the inert group, the ionization energy of outer shell electrons become very low. This makes the electrons available to take part in chemical reactions.

When particles are added pressure will do what and why
ElenaW [278]
Because area of the container has increased , there will be fewer of collisions per unit area and the pressure will decrease . Volume is inversely proportional to pressure , if the number of  particles and temperature is constant
( V = 1/P) and number of particle is proportional to pressure if average Kinetic energy of the particle remain same , the average force particle will remain same too so at some places and there will be more collision and there is greater pressure

Another chemistry question i’m not good at this at all:( has me stressed
adoni [48]

Answer:

Average atomic mass = 15.86 amu.

Explanation:

Given data:

Number of atoms of Z-16.000 amu = 205

Number of atoms of Z-14.000 amu = 15

Average atomic mass  = ?

Solution:

Total number of atoms = 205 + 15 = 220

Percentage of Z-16.000 = 205/220 ×100 = 93.18%

Percentage of Z-14.000 = 15/220 ×100 = 6.82 %

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

Average atomic mass  = (93.18×16.000)+(6.82×14.000) /100

Average atomic mass =  1490.88 + 95.48 / 100

Average atomic mass =  1586.36 / 100

Average atomic mass = 15.86 amu.
