What is the charge on lead with 78 electrons?
+4 On the periodic table, all elements are neutral. And that is the key to this problem. Lead (Pb) on the periodic table has an atomic number of 82. Therefore it has 82 protons. How many electrons would it need to be a neutral atom then? Obviously, 82! So if we have 82 electors and 82 protons we have neutral lead, but we don't have 82 electrons we only have 78. Therefore neutral lead lost negatively charged electrons. When you lose a negative you become more positive. So we have a charge of +4, since 82-78=4. In general the solution to this problem is: (Atomic Number) - (Number of Electrons) = (Net Charge)

How is metallic character shown on the periodic table?
The metallic elements on a periodic table may be represented by a certain color unlike those of other elements. Most periodic tables have elements in different colors, so try looking at the key that shows what each color represents for that element.

Just get to know the periodic table of the elements; that is the key to understanding valence electrons.
In a database files are called?
A database holds records in files that are called tables. Each table has a specific key that defines that table and each master key is unique.
The most useful source of chemical information about the elements is a?
periodic table. The periodic table provides a concise and organized overview of all the known elements, including their atomic number, atomic mass, and other key properties. It allows scientists to quickly access information about each element, such as its electron configuration, valence electrons, and chemical reactivity.

What does the background of the square indicate in the periodic table?
It depends on the key of the periodic table. Usually it signifies the type of element, e.g., alkali metals, nonmetal, noble gases, metalloid, rare eath metals, transition metals. However, it can mean other things.
