Transcript of BONDING IN MOLECULES
- 1. Chemistry PART 1
- UNDERSTANDING
- THE CONCEPT
- OF
- COVALENT BONDING
- 2. QUICK QUIZZZZZ.
- Only covalent compounds are called molecules.
- TRUE or FALSE?
- 3. BONDING IN MOLECULES Task What is bonding? What are Valence Electrons? Define the term Covalent. What is Covalent Bonding? www.sciencetutors.zoomshare.com
- 4. What is Bonding
- Bonding is the linking of atoms between a metal and non metal and or between two non-metals
- 5.
- What is Covalent Bonding?
- A covalent bond is a strong bond between two non-metal atoms .
- 6. Objective
- To explain that a covalent bond arises from a shared pair of electrons
- 7. Concept Of Valence Electrons
- The electrons in the outermost shell are the valence electrons
- These are electrons on an atom that can be gained or lost in a chemical reaction.
- 8.
- 9. VALENCE ELECTRONS AND STABILITY
- Many elements are stable when they contain eight electrons in their valence shell.
- 10. Calculating Valence Electrons Complete the table below: What are the symbols and valence Electrons of the following elements? Calcium Carbon Oxygen Potassium Chlorine Aluminium Magnesium Sodium
- 11. OCTECTOF VALENCE ELECTRON
- What is the symbol of Fluorine?
- What is the atomic number of fluorine?
- What is the electron configuration of fluorine?
- Two fluorine atoms, for example, can form a stable F2 molecule in which each atom has an octet of valence electrons by sharing a pair of electrons.
- 12. OCTECTOF VALENCE ELECTRON
- What is the symbol of Fluorine?
- What is the atomic number of fluorine?
- What is the electron configuration of fluorine?
- ANSWERS
- Fluorine symbol (F)
- Atomic number of fluorine is 9
- Electron configuration is 2, 7
- 13. QUICK QUIZZZZZZZ
- Explain how a pair of oxygen atoms can form an O2 molecule.
- What is the total valence electron of each atom of oxygen in a covalent bond?
- 14. Answers To Quick Quizzzzz
- Each atom of oxygen in a covalent bond has a total of eight valence electrons by sharing two pairs of electrons.
- 15.
- Covalent means sharing
- Complete the table below using your Periodic Table. Write down examples of non-metals that can share electrons.
- 16. Facts About Covalent Bonding
- When non-metals react with non-metals they share electrons and form a covalent bond.
- Single Covalent Bond
- One pair of shared electrons
- 17. Facts About Covalent Bonding
- When non-metals react with non-metals they share electrons and form a covalent bond.
- 2. Double Covalent Bond
- Two pairs of shared electrons
- 18. Facts About Covalent Bonding
- When non-metals react with non-metals they share electrons and form a covalent bond.
- 3. Triple Covalent Bond
- Three pairs of shared electrons
- 19.
- What is Covalent Bonding?
- A covalent bond is a form of chemical bonding that is characterized by the sharing of pairs of electrons between atoms, and other covalent bonds
- 20. COVALENT BONDING
- To introduce covalent bonding as the strong bonding between atoms in molecules
- What is the Atomic Number Of Chlorine?
- How many electrons are there in an atom of Chlorine?
- What is the electron configuration of Chlorine?
- How many more electrons does chlorine need to have a full outer shell?
- 21. COVALENT BONDING
- To introduce covalent bonding as the strong bonding between atoms in molecules
- What is the Atomic Number Of Hydrogen?
- How many electrons are there in an atom of Hydrogen?
- What is the electron configuration of Hydrogen?
- How many more electrons does Hydrogen need to have a full outer shell?
