Why gold is called inert metal​

Chemistry
1 answer:
astraxan [27]3 years ago
5 0

Gold has a heavy enough nucleus that its electrons must travel at speeds nearing the speed of light to prevent them from falling into the nucleus. This relativistic effect applies to those orbitals that have appreciable density at the nucleus, such as s and p orbitals. These relativistic electrons gain mass and as a consequence, their orbits contract. As these s and (to some degree) p orbits are contracted, the other electrons in d and f orbitals are better screened from the nucleus and their orbitals actually expand.

Since the 6s orbital with one electron is contracted, this electron is more tightly bound to the nucleus and less available for bonding with other atoms. The 4f and 5d orbitals expand, but can't be involved in bond formation since they are completely filled. This is why gold is relatively unreactive.

Hope it helps

elements on the right side of the periodic table differ from the elements on the left side in that elements on the right side
yarga [219]

Element  on the right side  of the periodic  table  differ from the elements on  the left side  in that elements on the <em>right  side  are non   metallic  and tends to be gases at room  temperature.</em>


<em>  </em><u>Explanation</u>

In the periodic table there element in  the right side , left side and those  which are in between.

  •  Example of element  in the right side is  fluorine  chlorine, neon, Argon   among others.
  • This element have higher  effective nuclear  charges   and  stabilize electrons more effectively.
  • there electrostatic  intermolecular  forces  are generally weak  therefore they  exist in  liquid or gaseous state.

In the Lewis dot structure for H2CCH2, how many bonds are between the carbon atoms?
AVprozaik [17]

Answer:

2

Explanation:

The compound H2CCH2 has the condensed formula C2H4. The name of the compound is ethene. The compound is unsaturated, that is, it contains multiple bonds. The compound has a formula which fits into the general molecular formulae of alkenes (olefins) which his CnH2n.

Olefins have a double bonds between the carbon atoms. That is , the two carbon atoms in Olefins are connected via a double covalent bond. This now implies that the two carbon atoms in ethene (C2H4) are connected by two covalent bonds in the lewis structure of the molecule as is common for Olefins.

Olenka [21]

Answer:

Dead bodies lose one degree Celsius per hour, which we could deduce that the person died 12 hours ago.

Explanation:

On the other hand, it is very important to take into account that this number of hours is very approximate, since not only does it vary greatly with the environment and the acclimatization of the environment in which the person dies, but also in this specific case, insulating clothing was presented , which made the loss of body heat much more difficult and could easily be more than 12 hours.

The minimum for this particular situation is 12 hours to 24 hours possible postmortem.
