Melting points tend to increase as you move from the alkali metals to the noble gases. Which is due in part to London Dispersion forces, or Van Der Walls.
as you move left to right, the atomic masses get bigger
There is an increase in the melting point of elements from left to right but this increase is not very sharp and continuous because there are a number of exception.
The atomic number increases one-by-one stepping to the right (within a specific period) in the periodic table.
The periodic table is arranged from left to right in the order of atomic numbers.
The atomic weight (not mass) increase from left to right in a period.
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
the choices are: A. They increase from left to right and top to bottom. B. They increase from left to right and bottom to top. C. They increase from right to left and top to bottom. D. They increase from right to left and bottom to top.
The atomic number and atomic masses increase as you move from left to right.
The atomic number increases from left to right. The atomic number also increases.However, there are few exceptions for atomic mass.
The atomic radius decrease from left to right in the periodic table.
The atomic number increases one-by-one stepping to the right (within a specific period) in the periodic table.
increases
B. are located on the right on the Periodic TableC. have a small atomic radius
The periodic table is arranged from left to right in the order of atomic numbers.
The atomic weight (not mass) increase from left to right in a period.
Lightest at Upper Left: Hydrogen, Then by row from Left to the Right and Then the next Rows down y'under. The same way as you'll read the lines in a book or letter.
Atomic radius usually decreases from left to right across a period of the periodic table.
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
the choices are: A. They increase from left to right and top to bottom. B. They increase from left to right and bottom to top. C. They increase from right to left and top to bottom. D. They increase from right to left and bottom to top.
