Answer and Explanation:
Isotopes are same in atomic number and different in atomic mass. Isotopes have same number of electron and proton but different number of neutron and due to same proton their atomic numbers are same and due to different number of neutron their atomic mass are different because neutron also take part in atomic mass

Explanation:
Answer:
Born-Haber Process - "Born-Haber process applies Hess's law to calculate the lattice enthalpy(<em>this is a thermodynamic term which equals to the total heat content of a system</em>), by comparing the standard enthalpy change of formation of ionic compound (from the elements) to the enthalpy required to make gaseous ions from the elements".
Explanation:
Now the calculations done for SRI2 are as follows:
- Enthalpy of Sublimation of Sr(s)= 164 kJ per mol,
- 1st ionization energy of Sr(g)=549 kJ per mol,
- 2nd ionization energy of Sr(g)=1064 kJ per mol,
- Enthalpy dissociation energy of I2(s)= 62.4 kJ per mol,
- Bond dissociation energy of I2(g)= 152.55 kJ per mol,
- 1st electron affinity of I(g)= -295.15 kJ per mol,
- Lattice energy of SrI2(s)=-1959.75 kJ per mol.
Note - the terms mentioned in the brackets are as, S- solid form, g- Gaseous form.
Answer:
B
Explanation:
In order for any conduction to take place it needs to go through a solid. Therefore it cannot travel through empty space
