Answer:
Explanation:
Elements that have most similar properties were placed in the same group on the periodic table and this is done based on the number of valence electron each of the element posses which allow them reach in a similar manner as a member of the same family. A group of element is placed on a a vertical column of the periodic table.
For all element with one valence electron they are labelled with 1A on the group, and are usually the first column followed by 2A until group 8.
1A element are known to be very reactive and form compounds with similar properties with other elements.
Answer:
The voltage or potential difference
Explanation:
What makes current flow in a circuit is the voltage or the potential difference.
This force is supplied by the battery or the mains electrical circuit.
- Every circuit requires the voltage to drive current through
- When a circuit is complete, the battery is able to overcome any resistance by the generating enough voltage which is the force to drive the current through.
Answer:
<h3>The answer is 4 atm </h3>
Explanation:
The new pressure can be found by using the formula for Boyle's law which is
Since we are finding the new pressure
From the question we have
We have the final answer as
<h3>4 atm </h3>
