Question

calculate total number of electrons in 160gm of 0^2- ions​

Answer 1

Answer:

10000000000000000000000000 electrons

Explanation:

Atoms form molecules and compounds by sharing electrons to create chemical bonds. Understanding the nature of this bonding begins by knowing the number of electrons associated with each atom. With the information from a periodic table of the elements, and some straightforward arithmetic, you can calculate the number of electrons based on the chemical formula of a material.

Analyze the chemical formula and write down the element types that comprise the compound as well as the number of atoms of each type. The first example, KNO3, contains the elements potassium (K—1 atom), nitrogen (N—1 atom) and oxygen (O—3 atoms). The second example, SO42-, contains the elements sulfur (S—1 atom) and oxygen (O—4 atoms).

Navigate to the periodic table of the chemical elements (see Resources) and find out the integer atomic number for each element identified in Step 1—the number that appears just above the chemical symbol for each element. In our example, the atomic numbers of the elements potassium (K), nitrogen (N), oxygen (O) and sulfur (S) are 19, 7, 8 and 16, respectively.
