Write the atomic symbol (a zx) for each of the following isotopes. a. z $ 8, number of neutrons $ 9 b. the isotope of chlorine in which a $ 37 c. z $ 27, a $ 60 d. number of protons $ 26, number of neutrons $ 31 e. the isotope of i with a mass number of 131 f. z $ 3, number of neutrons $ 4

Explanation:

a) O (oxygen) but there's not enough info to determine the isotope  

b) superscript-37 subscript-17 Cl  

c) superscript-60 subscript-27 Co  

d) superscript-57 subscript-26 Fe  

e) don't know what you mean here  

f) superscript-7 subscript-3 Li  

Edit:  

a) superscript-17 subscript-8 O  

e) superscript-131 subscript-53 I

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

explanation: no but i do not usually comment
