Answer:
The correct answer is the charges of the positive and negative copper ions cancel each other out.
Explanation:
A copper metal having no net charge means that it is a neutral atom. A neutral atom means that total number of protons is equal to the total number of electrons.
Answer:
NaCi + LiCl is the correct answer
Explanation:
an ion is an atom with a met electric charge due to the loss or gain of one or more electrons and an isotope can be in 2 forms of the same element that contain equal numbers of protons but a different numbers of neutrons in their nuclei and hence differ in relative atomic mass but not in chemical properties
Answer:
A lot
Explanation:
- As you go down a group, the elements get larger in size
- All of the elements of the same group have the same # of valence electrons
- As you go to the right of a period, the # of electrons in the outermost shell increases
- The elements at the top right of the table have the highest electronegativity
- Groups 13 through 17 are nonmetals
- The last group contains noble gases
etc.
