In the reaction of silver nitrate and sodium chloride to produce solid silver chloride, sodium ions and nitrate ions are . spectator ions gases solvents liquids molecules

spectator ions

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The total ionic chemical equation is:

The ions which are present on both the sides of the equation are sodium and nitrate ions which are called as spectator ions and hence are not involved in net ionic equation.

Francium (Fr) has the lowest ionization energy in Group 1 because -its 1 valence electron is very far from the nucleus, so little energy is needed to remove it

Ionization energy is the energy that an atom needs in the gas phase to release its electrons

the atomic number of the elements in group 1A:

The atomic number indicates the number of electrons and protons.

atomic number = number of electrons = number of protons

As the number of electrons increases from top to bottom, the number of shells will increase(the radius of the atom tends to get bigger) so that the tendency to remove the outer electrons is easier and the ionization energy is also smaller(the attraction of the atomic nucleus to the outer electrons  (valence electron) weaker)

Ionization energy is the attraction of the nucleus to electrons, not protons

The valence electrons in group 1 are the same which is 1

The mass number is not related to the ionization energy
