Answer:
I need more information. What is the question?
Answer:
Barium-138
Explanation:
The mass number is the atomic number + the number of neutrons. ... Identify the atom whose nucleus is composed of 56 protons and 82 neutrons. Barium-138 (the number of protons identifies the atom) Gallium has two naturally occurring isotopes: Ga-69 with a mass of 68.9256 amu and a natural abundance of 60.11% and Ga-71.
Answer:
Thus the order of covalent character will be
DG < EG < DF < DE
Explanation:
The electronegativity decides the nature of bond formed between two atoms.
More the difference in electronegativity more the ionic character in the bond formed.
Let us check the electronegativity difference between the elements forming molecules
a) DE :
3.8-3.3 = 0.5
b) DG :
3.8-1.3 = 2.5
c) EG
3.3-1.3 = 2
d) DF
3.8-2.8 = 1.3
So the maximum ionic character will be in DG and minimum in DE
Thus the order of covalent character will be
DG < EG < DF < DE
