Answer:
C. ns² np^5
Explanation:
An electron gets more electro-negative as it increases in number of electrons until it shell gets filled up. At the point when its shell is filled up, the electron becomes neutral; i.e. not positive and not negative.
Only ns² np^5 satisfies this condition; reason being that it has higher electrons
Be(g) + e + 241 kJ ==> Be^-(g) EA = +231 kJ/mol. (endothermic)
Considering the example above
Also, electron affinity is referred to as the amount of energy absorbed when there's an additional electron to an isolated gaseous atom which forms an ion with a 1- charge by assigning a positive value when energy is absorbed and a negative value when energy is released
Explanation:
I think it's probably like this.
The assumption that the cosmic microwave background
is the remnant of the environment at the time of the big bang
or very shortly after it explains very well what we observe now.
So it is the current prevailing theory. "Believe" is not involved.
Answer: Government passing regulatory laws
Car emissions testing
Carpooling and less driving overall
Air pollution results when a mixture of particles and gases that can reach in harmful concentrations both outdoors as well as indoors. This increase in concentration can lead to rise in the temperatures and global warming it is also related with the health hazards. Soot, smoke, pollen, carbon dioxide, carbon monoxide and methane are the examples of the common pollutants.
Government passing regulatory laws: The government can ban some of the fossil fuels to prevent air pollution, and some vehicles which are likely to emit more partially combustible gases.
Car emission testing: Nowadays, cars and other vehicles are equipped with catalytic converters which converts the uncombustible gaseous products into less harmful gases which are emitted from the vehicle. The car gas emission testing should be performed to either allow a vehicle or ban the movement of the vehicle.
Carpooling and less driving overall: Carpooling is the sharing of one vehicle with more than one individual. This will prevent the need of others to drive another vehicle. The less the number of vehicles on the road the lesser will be the emission of gases and less pollution will be caused.
