Hello there!
Electronegativity is the atom's tendency to attract electrons in a chemical bond
There are two trends to electronegativity:
- Electronegativity increases from bottom to top in a group (Li has a greater electronegativity than Fr, for example)
- Electronegativity increases from left to right across a period (the further right the group, the greater the electronegativity)
Looking at a period table, Sb, Sn, Te, and I are all in the same period, so we'll need to decide which element has the highest electronegativity based on the group.
- Sn belongs to group 4A (group 14)
- Sb belongs to group 5A (group 15)
- Te belongs to group 6A (group 16)
- I belongs to group 7A (group 17)
As I belongs to group 7A, the group that is the farthest right based off of the options given, I has the highest electronegativity
Hope this helps!

Answer:
196 gdm-3
Explanation:
There are two major units of concentration, moldm-3 and gdm-3. The first unit refers to molar concentration while the second unit refers to mass concentration. Both units are useful in chemistry when describing the concentration of solutions as deemed expedient in each particular case.
Here we are required to compute the mass concentration from the molar concentration. We must recall that; mass concentration= molar concentration × molar mass
Let us first obtain the molar mass of H2SO4 from the relative atomic masses given=
2(1) + 32 + 4(16) = 98 gmol-1
Molar concentration of H2SO4 = 2 moldm-3
Mass concentration= 2 moldm-3 × 98 gmol-1
Mass concentration = 196 gdm-3
Answer:
Isotopes of an element have same number of protons but different number of neutrons. Which means isotopes of an element have same atomic number but different mass number.
The chemical property of an element is determined by the number of electrons. And as all the isotopes have same number of electrons, they have same chemical properties.
Thus as isotopes of an element have same atomic number , they have same number of electrons and protons. As they have different mass number, the number of neutrons will be different. Hydrogen has three isotopes , 
, 
and 
. Thus has no neutron.
