Answer:
Elements in the same group have the same number of valence electrons.
Explanation: Science.
A cone of depression occurs in an aquifer when groundwater is pumped from a well. In an unconfined aquifer, this is an actual depression of the water levels. In confined aquifers, the cone of depression is a reduction in the pressure head surrounding the pumped well.
The total amount of water in the beaker is 0.8 Liters
calculation
convert 300 Ml in liters
that is 1 L = 1000 Ml
? = 300 Ml
by cross multiplication
1 L x300 Ml/ 1000 Ml = 0.3 Ml
total is therefore = 0.5 Ml + 0.3 Ml = 0.8 Liters
Here is the answer to the question above. Ions are made from neutral atoms wherein, it has the same number of protons and neutrons as the neutral atoms. The only difference is that they have difference number of electrons. Hope this answers your question. Have a great day!
