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
Answer:
True
Explanation:
The greenhouse effect is the process whereby there is radiation from a atmosphere planet and the planet increase the temperature of the planet's surface to a temperature above normal.In this process the Earth's atmosphere becomes thicker with the influence substances such as gases
and the radiation coming from the sun is trapped, then the Earth becomes warmer. Green house effect is seen in global warming.
Carbon neutral can be described as a process of removing huge amount of carbon dioxide from the atmosphere in order to achieve zero carbon neutrality.It is also reffered to as carbon neutrality, and this can be achieved by actions of organizations, businesses and individuals .
Carbon neutral can be achieved in two ways;
: 1.) Maintaining a balance between carbon dioxide emissions and carbon removal by means of the process called carbon offsetting
2 ) the process of removal of carbon dioxide from the atmosphere in order to balance up emissions in another place.
Carbon positive is crucial to increase the positive influence of our daily activities on climate change and our resources.
while reduce the negative effect of our activities and business on evironment.
Therefore, the practice of making operations "carbon neutral" is a way to offset whatever damage is being done to the environment due to greenhouse gas emissions by purchasing credits from "carbon-positive" projects to balance out emissions is true because the harmful gasses that is been released to the atmosphere is balance up by the carbon neutral process hence the reduction in green house effect.
