Final answer:
Atoms achieve stability by gaining, losing, or sharing electrons to match noble gas configurations. Metallic elements become positively charged when forming ions by losing electrons to reach stability.
Explanation:
Atoms often gain, lose, or share electrons to achieve the same number of electrons as the noble gas closest to them in the periodic table. When metallic elements become ions, they become positively charged as they lose electrons to attain stability.
For example, sodium (Na) forms a 1+ cation by losing one electron to achieve a stable electron configuration similar to neon (Ne), a noble gas. This helps to illustrate the concept of ionic bonding and how atoms strive to attain stability through electron transfer.
