How does a lithium cation compare to a lithium atom? How does a lithium cation compare to a lithium atom ? The cation is smaller. Which prediction is supported by the information in the table? K will give up an electron more easily than Br. When electrons are removed from the outermost shell of a calcium atom the atom becomes. NOT: How does a lithium cation compare to a lithium atom ? C - The cation is smaller. Which correctly summarizes the trend in electron affinity? B - It tends to be more negative across a period. Which is true of transition metals when moving from left to right on the periodic table? So in the previous video we already know that lithium has an atomic number of 3 so there are three protons in the nucleus. In a neutral atom of lithium the number of electrons equals the number of protons and so we know there are three electrons in lithium here. The electron configuration is 1s2 2s1. So the first ionisation energy for lithium refers to the energy required to remove 1 electron (e-) from an atom of lithium which is in the gaseous state (Li (g)). The products of the reaction are an electron and a gaseous lithium ion with a charge of +1 (Li + (g)). We can represent the first ionisation of each group 1 element as shown below: The order in decreasing size would be Cl- > F- > Na+ > Li+. This can be explained by the following logic. Cl- would be the largest because it has the largest number of electrons i.e. 18. So the electron- electron repulsion would be maximum in th... Why does lithium have the largest atomic radius ? ... because it has less number of protons in nucleus as well as less number of electrons in its orbit as ...
