Answer:
The atoms on left side are larger than the atoms on the right side of the periodic table because those on the right have more proton's.
Explanation:
As we travel along a period in a periodic table then the atomic radii decreases
This is because as we travel along a period we have that the atomic number of the atoms increases which means the the number of proton's increased
But the electron's add to the same outer shell throughout the period , which means the effective nuclear charge increases which pulls the outer electrons toward's the nucleus and the size decreases.
Therefore the atoms on left side are larger than the atoms on the right side of the periodic table because those on the right have more proton's.
Answer:
9.63 L.
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
So the consumed amounts of hydrochloric acid and bromine are the same to the beginning based on:
In such a way, the yielded moles of hydrobromic acid and chlorine are:
Thus, the volume of the sample, after the reaction is the same as no change in the total moles is evidenced, that is 9.63L.
Best regards.
Your answer is going to be B. at the focal point of the lens. :)
Answer:
chongus because he's the only good one
Along each row of the periodic table, the atomic mass increases from left to right.
Explanation:
The elements in the periodic table are arranged based on rows and periods by increasing atomic number.
The periodic table has rows from left to right and columns from up and down. These rows are called periods and columns are called groups.
The electron organization in an atom explains about the shape and the elements in the same column have similar chemistry. The elements in each column have the same valence shell electron configuration and they have similar properties.
