Ions, atoms, and isotopes Flashcards
1
Q
What happens to an atom if it gains one or more electrons
A
It gains an overall negative charge because it has more electrons than protons and it becomes an anion
2
Q
What happens to an atom if it loses one or more electrons
A
It becomes a cation because it has more protons than electrons
3
Q
What will all samples of different isotopes of an element have in common and why
A
They always have the same chemical properties, because their reactions depend on their electronic structures.
4
Q
Isotope
A
Atoms that have the same number of protons but different number of neutrons, i.e, they have the same atomic number but different mass numbers.
5
Q
Ion
