When looking across a period of the periodic table from left to right when happens to the atomic number and electronegativity?
As you move from the left to right, the atomic number increases. Also, the electronegativity increases.
What happens to the number of neutrons in a typical atom moving from left to right on the periodic table?
From left to right , atomic number increases. Number of neutrons also increases.
What trends do you notice about the atomic number and atomic mass as you move left to right across the periodic table?
The atomic number increases from left to right. The atomic number also increases.However, there are few exceptions for atomic mass.
Is the atomic number 10 to the right or left of the atomic number 9?
It is in the same direction of reading: left (9) lower, right (10) higher
What happens to the atomic size of the atoms as you go from left to right of the periodic table?
The atomic radius decrease from left to right in the periodic table.
What trends do you notice about the atomic number and atomic mass as you move left to right across the table?
they increase by one going from left to right totally a guess
How does atomic number change as you move from left to right?
I'm guessing you are acking Atomic Radius. The atomic radius decreases and you go left to right because the shielding effect from the lower electrons stays almost constent while the elements gain more protons adding to the effective nuclear charge pulling the electrons closer to the nucleus.
When you go left to right on the periodic table what happens to the atomic radius?
Yes. The atomic radius increases down the group. This is because number of shells increases down the group.
When you move across the periodic table from left to right what happens to the number of protons contained by each element?
the numbers increase (going right) and decrease (going left)
How does the atomic number change in a period?
When going left to right across a period, the atomic number of element increases.
What happens to the atomic number as you go from left to right across the periodic table and why does this happen?
Periods on the periodic table refer to the rows of elements. As the elements progress to the right, the atomic numbers increase, usually in steps of 1.
An increase in the atomic number the atomic radius moving from left to right across a period.?
decreases
