When you see a long dash joining two elements in the structural formula of a chemical molecule you can assume that the chemical bonds in the compound are simple bonds.
In the representation of chemical molecules long dashes are used to represent simple bonds since these bonds are longer than double and triple bonds, which are represented by = and ≡ respectively.
Answer:
Gd(g) → 
, 
→ 
, 
→ 
Explanation:
Ionization energy is the energy required to remove an electron from a gaseous atom or ion.
The first ionization energy is the energy required to remove the valence electron(outermost) from a neutral atom:
Gd(g)→
The second ionization energy is the energy required to remove next/second electron from 
ion. The second ionization energy is always higher than the first:
(g) →
The third ionization energy is the energy required to remove third electron from 
ion:
(g) →
