Which of the following symbols provides more information about the atom: 23na or 11na? explain.

The correct answer is

Explanation:

The general representation of an isotope is

where,

A = atomic mass of the element

Z = atomic number of the element

X = symbol of the element

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

Atomic number = number of protons = number of electrons

Atomic mass is defined as the sum of number of protons and neutrons that are present in an atom.

Atomic mass = Number of protons + Number of neutrons

Atomic number = 11 (Sodium)

Mass number = 23

So, from this we can easily get the number of protons, number of electrons and number of neutrons present in the given element.

Atomic number = 11

So, from this we can only get the number of protons and number of electrons present in the given element.

Hence, the correct answer is

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i
