Atoms of the group 15 elements tend to react to form _______ ions.
A. 5+
B. 32
C. 52
D. 3+
My guess is D. Which is correct?
There are 5 electrons in the outside shell. Those atoms have oxidation states of +5, +3, and -3. Technically almost none of the elements have "IONS" with ANY charge but I think the answer to this question is A.
i just took exam. the answer is b.
To determine which ions group 15 elements tend to form, we need to look at the periodic table. Group 15 elements are also known as the "nitrogen family" and include nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi).
To find the answer, we need to understand the number of valence electrons for each element in this group. Valence electrons are the electrons in the outermost energy level of an atom, and they play a crucial role in determining the chemical behavior of elements.
For group 15 elements, the number of valence electrons is equal to the group number minus ten. In this case, since it is group 15, the valence electrons would be 5 (15 - 10 = 5).
Now, to determine the typical ion formed by these elements, we need to consider their tendency to gain or lose electrons. Since group 15 elements have five valence electrons, they have a strong tendency to gain three electrons to achieve a stable electron configuration (a full outer energy level with eight electrons).
Therefore, the correct answer is:
D. 3+
Group 15 elements tend to react to form ions with a charge of 3+ by gaining three electrons.
