Answer:
Explained below.
Explanation:
A tennis player with two sneakers wouldn't bond to any other tennis player because he is already stable and complete with the 2 and doesn't need another players assistance to make him stand well.
However, helium atom with two electrons wouldn't bond to any other atoms because it is stable. This stability arises from the fact that it has two protons and 2 electrons, of which the 2 electrons completely fill its valence shell/outer most shell to make it neutral.
Answer:
A3+ and B-
Explanation:
Elements in group 13 have outermost electron configuration, ns2np1 hence they form trivalent positive ions.
Elements in group 17 have outermost electron configuration ns2np5 hence they form univalent negative ions.
This implies that, if element A is in Group 13 and element B is in Group 17, the ions formed are A3+ and B-.
Answer:
Explanation:
Hello,
In this case, we could considering this as a redox titration:
Thus, the balance turns out (by adding both hydrogen ions and water):
Thus, by stoichiometry, the grams of Fe+2 ions result:
Finally, the mass percent is:
Best regards.
