Lesson 21 Molecular Shapes

Chem-C. 21 Molecular Shapesand the answer is
How many covalent bonds make up a bond angle. Is it 1....2....or.....4...? 2
True or False : A bond angle is formed between the covalent bonds linking three atoms? True
Select the word that makes the following sentence correct.--Electron pairs in a molecule are as (close to) or (far apart) from each other as possible. far apart from
The presence fo an unshared electron pair in a molecule causes the bond angles to be slighty (LARGER) OR (SMALLER) than they otherwise would be. Smaller
A three atom molecule with a bent shape is (CO2) or (H20) H20
What is the bond angle between the atoms in a molecule of oxygen gas? ( 02)..Explain your answer.. There is none because two-atom molecules are linear.
What is the shape of a molecule made of two atoms? straight line (linear)
Explain why the shape of a molecule depends on the electron pairs around the central atom. Electron pairs repel other electron pairs strongly and unshared electron pairs repel shared pairs even more strongly.
What is the chemical formula that tells the kinds and realtive numbers of atoms of each kind in an ionic compound formula of an ionic compound
A group of atoms of different elements that act together to form an ion are called..... a covalent bond......a ionic bond.....a ottaihcolrm....or a radical radical
What is a ottahcolrm ? Mr. Lochiatto ...spelled backwards
