1. On the basis of Thomson’s model of an atom, explain how the atom is neutral as a whole. Ans:As per Thomson’s model of an atom, the number of electrons and the number of protons are equal in an atom. Electrons are positively charged and protons are negatively charged, hence the...
Describe the distribution of mass and charges within an atom. Deduce the numbers of protons, neutrons and electrons present in both atoms and ions given proton and nucleon numbers. Describe the contribution of protons and neutrons to atomic nuclei in terms of the proton number and nucleon number...

When in an atom the number of electrons is greater than the number of protons, then the atom carries an extra negative charge. These ions are called an atomic anion.Answer and Explanation: The number of protons in all the atomic anions is 8. Hence, the atomic number ...
3G, H). At the beginning of the reaction, no formate is found in the synthesis mixture; however, the start of the heating induces its slow accumulation via hydrolysis of DMF, catalyzed by the protons formed during deprotonation of terephthalic acid. The formation of formate finishes after the...
