elements in group Ia - IVa have an oxidation number equal to the positive number of the group.example oxidation of K = +1, K is in group 1. elements in group Va - VIIa have an oxidation number equal to the group number minus 8. for example oxidation of O is -2, group number 6a minus 8 equals -2. as for the rest of the elements in groups 1b to 8b i have no idea and am searching for the answer.

∙ 9y agoIn the Periodic Table, an element's atomic number indicates the number of protons in its nucleus. If the number of electrons in its orbit is known, its ionic charge can be easily determined by subtracting the number of electrons from the atomic number.

1A = 1 valance electron of the alkali metals.
4A = 4 valance electrons of the carbon family.
Remember, transition metals have varying oxidation states. The can donate various numbers of electrons though the top numbers generally give an accurate valance number.

How do you determine the electrical charge of an atom?
I believe you use a periodic table to find the specific element you're looking for.
What is eleventh element on the periodic table?
Sodium is the eleventh element on the periodic table.
What element on the periodic table weighs 19.32?
No element has an atomic weight of 19.32 on the periodic table.
How can the periodic table be used to predict the properties of an element that has not been discovered?
It can't. the properties of an element determine it's group placement, without knowledge of these properties (or, indeed, the element itself) it would be impossible to place an element in it's proper place on the periodic table.
Summarize how the periodic table is organized and tell this organization is useful?
The number of electrons an element has determine the organization. This table helps in making predictions about how an element will chemically react.

What is the electrical charge on a single atom of an element listed on the Periodic Table?
The atom is neutral.
What is the name of the element As in the periodic table?
The element abbreviated with As on the periodic table is Arsenic
What is eleventh element on the periodic table?
Sodium is the eleventh element on the periodic table.
What is the difference between groups and families on the periodic table?
families determine the energy level of an element and groups determine their properties.
How do you determine the mass of an element?
The mass of an element is the sum of the protons and neutrons in an atom. It is usually listed right on the periodic table.
What can you tell about the properties of this element?
The periodic table can be used to quickly determine characteristics (number of valence electrons for example) of an element.
What is a group in a periodic table.?
A group in Periodic Table is the column of element in periodic table
Which list pairs each element in the periodic table with the correct charge of its ion?
Na:positive Ci:negative
Is copper wiring a mixture compound or element?
Copper is on the Periodic Table, anything on the periodic table is an element so copper wire is made from an element.
