How does a sodium atom change into a sodium ion?
A) By gaining an electron
B) By losing a proton
C) By losing an electron
D) By gaining a neutron
Correct Answer:
C) By losing an electron
Explanation:
A sodium atom changes into a sodium ion by losing an electron. When an atom loses one or more electrons, it becomes positively charged and is called an ion. In the case of sodium (Na), it loses one electron to become a sodium ion (Na+), which has a +1 charge. Options A, B, and D do not accurately describe the process of sodium atom to sodium ion transformation.
