Question

Let's tie this in with what we learned about metals and nonmetals earlier We said that metals Is sodium a metal or a nonmetal? Looking at our example above, did sodium donate or accept an electron? We also said that nonmetals Is chlorine a metal or a nonmetal? Looking at our example above, did chlorine donate or accept an electron? electrons to become electrons to become Why do we care? Well, when sodium donates an electron to become a positively charged cation, and chlorine accepts an electron to become a negatively charged anion, this creates an attraction. (Think of it like "opposites attract.") This attraction leads the two ions to bond to one another, forming an ionic bond. See how simple that is? Chemistry UNIT 241

Answer 1

1. Metals LOOSE electron to become CATION

2. Sodium is METAL

3. sodium DONATED electron

• Metals tend to loose electron in order to achieve noble gas configuration.
• This lost (or donation) of electron means that element is loosing negative charged and therefore it will have more of positive charge. This ion is called as Cation
• Sodium looses (or donates) one electron to form Na+ cation

4. Non metals GAIN electron to become ANION

5. Chlorine is NON-METAL

6. chlorine ACCEPTS electron

• Unlike metals, non-metals tend to gain (or accept) electron in order to achieve stable noble gas configuration
• They do so by gaining/accepting electron which means that they will now have excess of negative charge (as protons or positive charge remains unchanged most of times) and thus become Anion
• Chlorine accepts an electron and become Cl- anion
