For better representation, let me rewrite the electronic configuration:
<span>1s</span>²<span>2s</span>²<span>2p</span>⁶<span>3s</span>²<span>3p</span>⁶<span>4s</span>²<span>3d</span>⁴
The exponents represent the number of electrons in the designated subshell. Thus, the total number of electrons are:
# of electrons = 2+2+6+2+6+2+4 = 24
Assuming this is in neutral state, the element with an atomic number of 24 is Chromium. Thus, the answer is Cr.
Answer:
using public transportation
Explanation:
With the use of public transport, there will be a reduction in the number of cars on the streets, this reduction will cause a reduction in the gases released by cars into the atmosphere, which will result in a reduction in air pollution.
Explanation:
Causes of climate change are:
1.)Smoke from Vehicles and industrial activities
2.) Burning of polythenes.
3.) Because of green house effect
Effects are:
