How many electrons would be found in the Ion who’s symbol is I-
Vesnalui [34]

Answer:

54

Explanation:

Given symbol of the element:

                   I⁻

Number of electrons found in an ion with the symbol:

  This is a iodine ion:

         For an atom of iodine:

                   Electrons  = 53

                   Protons  = 53

                   Neutrons  = 74

An ion of iodine is one that has lost or gained electrons.

For this one, we have a negatively charged ion which implies that the number of electrons is 1 more than that of the protons.

  So, number of electrons  = 53 + 1  = 54

The number of electrons in this ion is 54

Does every rock go through the rock cycle, from igneous to sedimentary to metamorphic each time around???
Alex17521 [72]
No it does not ALWAYS go through all the stages because each rock forms differently at different rates. Igneous rock can weather to sediement rock, or melt to magma, however this does not necessarily mean it does this every time. It all depends on the temperature, wind, and pressure/heat.
