which element would have 2 electrons and +1 charge
which element would have 18 electrons and +3 charge.
I know you didn't expect to get this answer but the answer to both is none. ALL elements have a zero charge. You may want to rephrase your question.
Reworded:
Enter the symbol of the element which would have 18 electrons and +3 charge
and the element with 2 electrons and +1 charge
Another problem. Do you want 18 electrons in the outer shell for the first one or is that 18 electrons total. If total then I would go with Sc (21 total - 3 electrons = 18 and a +3 charge) so Sc^3+.
The second one is Li^+. It has 3 electrons to start and when it loses one that leaves two and a +1 charge.
thanks so much!
To determine which element would have 2 electrons and a +1 charge, we need to understand the concept of valence electrons. The charge of an element is determined by the number of electrons gained or lost relative to its neutral state.
Elements in the periodic table are organized by increasing atomic number. The atomic number is the number of protons in an atom's nucleus, which also determines the number of electrons in a neutral atom.
For an element to have a +1 charge, it means that it has lost one electron. Based on this, we look for elements in the periodic table that have a total of 3 electrons (2 valence electrons plus 1 extra electron). One such element is Lithium (Li), which has 3 electrons in total, with 2 valence electrons in its outermost energy level (shell) and one electron in the lower shell. When Lithium loses its outermost electron, it becomes positively charged with a +1 charge.
For the second question, to find an element with 18 electrons and a +3 charge, we apply the same reasoning. A +3 charge indicates that the element has lost three electrons relative to its neutral state.
To determine the element, we need to find one with 18 total electrons (15 valence electrons plus 3 extra electrons). One element that fits this description is Chlorine (Cl), which has 17 electrons in total, with 7 valence electrons. When Chlorine loses three electrons, it gains a +3 charge.
Therefore, the element with 2 electrons and a +1 charge is Lithium (Li), and the element with 18 electrons and a +3 charge is Chlorine (Cl).
