What is the atomic mass and the type of electrical charge for al on the periodic table?
Atomic Mass of aluminium (Al) = 26.98
Aluminium has 3 valence electrons and hence will form Al3+ cation.
Note: The symbol should be Al and not al

What makes the atomic radius change along the periodic in the periodic table?
Along a period, nuclear charge increases. hence, atomic radius decreases.
When you go across the periodic table how does the atomic size go?
Atomic size tends to decrease as you move from left to right across a period on the periodic table. This is due to increasing effective nuclear charge, which attracts the electrons more strongly and pulls them closer to the nucleus.
What has a 5.09 on the periodic table?
Platinum has a relative atomic weight of 195.09(you will not find 5.09 anywhere else on a periodic table.)
What happens to the atomic radius when you go from left to right on the periodic table?
As a general rule, when moving left to right on the periodic table the atomic radius decreases due to increasing electromagnetic attraction of the nucleus to the electrons.
What does the atomic number and atomic mass have to do with the arrangement of the elements on the periodic table?
The elements on the periodic table are arranged in order of increasing atomic number.
How does the atomic radius increase or decrease horizontally on the periodic table?
Atomic radius decreases horizontally in periodic table. This is due to increase in nuclear charge.
What make the atomic radius change along the periodic in periodic table?
Along a period, nuclear charge increases. hence, atomic radius decreases.
What makes the atomic radius change along the periodic in the periodic table?
Along a period, nuclear charge increases. hence, atomic radius decreases.
How does atomic number explain the arrangement of the periodic table?
According to the modern periodic table "Elements are the periodic function of their atomic number".They are arranged in increasing atomic no. in the periodic table.
What is the electrical charge on a single atom of an element listed on the Periodic Table?
The atom is neutral.
Why is copper a better conductor than gold when it is higher in the periodic table?
been at the top of the periodic table and at the bottom has nothing to do with electrical properties , it has to do with the atomic wheights and numbers. copper is the best coductor in the periodic table.
What is the atomic number of permanganate on the periodic table?
The atomic number of permanganate on the periodic table is 25.
What is the atomic number of scandium on the periodic table?
The atomic number of scandium on the periodic table is 21.
What is the atomic number of uranium on the periodic table?
The atomic number of uranium on the periodic table is 92.
When you go across the periodic table how does the atomic size go?
Atomic size tends to decrease as you move from left to right across a period on the periodic table. This is due to increasing effective nuclear charge, which attracts the electrons more strongly and pulls them closer to the nucleus.
Is the periodic table organized by atomic numbers?
The Periodic Table is.
What is the atomic radius of helium and how does it compare to other elements in the periodic table?
The atomic radius of helium is about 31 picometers. Helium has one of the smallest atomic radii among all the elements in the periodic table due to its small size and high nuclear charge.
