Interpretation: The stability of Lithium atom needs to be compared with ion,
Concept introduction:
All of the atoms tend to attain stable structure by losing electrons or gaining electrons to get a complete octet. In other words, all atoms follow octet rule which describes that the group elements will bond with other group elements in such a way that each atom will have eight electrons in its valence shell which is similar in configuration as noble gas.

Answer to Problem 1SSC
The Lithium ion is more stable than its atom as the Lithium ion has a complete octet.
Explanation of Solution
In order to compare the stability of Li atom with that of
Li atom has
Comparing both the structures, it can be seen that Lithium ion is more stable than Li atom as it has a stable complete electronic configuration.
The Lithium ion is more stable than its atom as the Lithium ion has a complete octet.

- NH3 decomposes through an equilibrium reaction between NH3, H2, and N2. Only one of the options is correct:(A). The mechanism of the NH3 decomposition reaction must necessarily involve the collision of two NH3 molecules to induce a rearrangement of the atoms in this molecule.(B). The molecular weight of the NH3 decomposition reaction is 2 since two NH3 molecules must collide.(C). The rate of the NH3 decomposition reaction must be greater than that of NH3 synthesis, since the former requires two molecules to collide and the latter, four.(D). The NH3 decomposition reaction cannot occur in a single step.arrow_forwardGiven the equilibrium A2 + B2 ⇌ 2 AB where k1 is the rate coefficient of the forward reaction and k-1 is the rate coefficient of the reverse reaction, with the forward reaction being first-order in A2 and B2, and the reverse reaction being second-order in AB. Equilibrium will be reached later if the relative values of the constants are:(A) k1 high and k-1 high(B) k1 high and k-1 low(C) k1 low and k-1 high(D) k1 low and k-1 lowarrow_forwardA 2-step reaction has the following mechanism: | 1. (fast) R2 R+R 2. (slow) R+Q K₂ P k_1 What series does it have? (A). v= - = (k + k1 − k-1)[R2][Q] (B). v=-k₁[R₂] + k₁[R]² - k₂[R][Q] (C). v=k₂[R]²[Q]² (D). v = k[R₂]1/2[Q]arrow_forward
