It is false. The salt bridge is not a path for electrons, but a path for ions to flow from one half-cell to another. It help to balance the charge between the oxidation and reduction vessels.
The number of protons would be equivalent to the number of electrons if the net charge on the atom is 0.
The periodic table is an important but rather dry scientific tool. It lists all the chemical elements, ordered by their atomic numbers. Elements with similar behavior are grouped in the same column (called a group), with metals generally on the left and non-metals (gases) on the right. Rows are called “periods” - hence, periodic table.
Is this what you looking for ???
[B][C] / [A]^2
Products raised to the coefficients over reactants raised to the coefficients
C)
Metallic solids consist of metal ions which are surrounded by delocalized electrons.
