Q2PeTa2 - SCIENCE
Tekst Storyboardowy
- Good day Class! Today we are going to learn about Ions and the two types of Ion, Cation and Anion. So are you ready to learn?
- Yes teacher!!
- In other words, there is an imbalance in the number of protons (positively charged particles) and electrons (negatively charged particles) in a chemical species.
- First off, what is an ion? An ion is defined as an atom or molecule that has gained or lost one or more of its valence electrons, giving it a net positive or negative electric charge.
- As I've said earlier, there are two types of ions, can anyone remember what are the two? Yes. Tiffany?
- If I'm not mistaken, I think it's Cation and Anion?
- Cations are ions that have positive charge because the number of protons in the species is greater than the number of electrons. The formula for a cation is indicated by a superscript following the formula that indicates the number of the charge and a "+" sign.
- Anions are ions that have negative charge. In anions, there are more electrons than protons. The number of neutrons is not a factor in whether an atom, functional group, or molecule is an anion. Like cations, the charge on an anion is indicated using a superscript after a chemical formula. And that's all for today, Can anyone share what they learned today?
- That's right Tiffany! So class, Ions can be grouped into two categories, the Cation and the Anion
- I learned that Cations are ions that have positive charge.
- I learned that there is an imbalance in the number of protons (positively charged particles) and electrons (negatively charged particles) in a chemical species.
- I learned that Ions have two different categories, the Cation and Anion.
- I learned that Anions are Ions that have negative charge.
