Explanation:
The sum of total number of protons present in an element is known as atomic number of the element.
- As atomic number of Cs is 55.
And, it is known that for a neutral atom the number of protons equal to the number of electrons.
Since, no charge in present on given Cs atom it means that it is neutral in nature. Hence, number of protons and electrons present in Cs are 55.
- For Ba, it is also neutral in nature and atomic number of barium is 56. Hence, number of protons and electrons present in Ba are 56.
- For S, there is no charge on it so it is also neutral in nature. Atomic number of S is 16. Hence, number of protons and electrons present in S are 16.
3 Sig FIgs in 303,000 mm
Any nonzero is a sig fig.
Any zero between two non zeros is a sig fig.
Push the pushbutton to the first stop before inserting the tip into the solution, and then put the tip in the solution tube.
Number 1 do a data table on paper and do as it was said, then go into Microsoft Excel and put your chart in. For 2 make a line graph(as stated) and do what it tells you.For 3 do as said with the line graph or whatever it should look somewhat like a math chart(the coordinate plane) and do as said. For number 4 help him/her study the charts and analyze the difference between the two. And for number 5 make him/her choose one element and research and write down the questions.
