Electrons and Bonding Flashcards
What is an orbital?
The reigon of an atom that can hold two electrons with opposite spins.
What shape are S orbitals?
They are spherical in shape.
How many electrons can an S Subshell hold.
Each S subshell can hold two electrons.
What shape is a P orbital?
They are dumbell shaped. (like a figure of eight)
How many electrons can a P subshell hold.
Each P subshell can hold six electrons.
How many electrons can a D subshell hold.
Each D subshell can hold ten electrons.
How many electrons can an F subshell hold.
Each F subshell can hold fourteen electrons.
What shape is a D and F orbital?
Complex.
Which block on the periodic table are groups 1 and 2 in.
S Block
Which block on the periodic table are the transition metals in?
D Block
Which block on the periodic table are groups 3 - 0 in?
P Block
Which subshell fills first, 3d or 4s?
4s will fill before 3d
What is an ionic bond?
The electrostatic force of attraction between positvly charged ions and negativly charged ions.
Ionic bonding happens between ________ and _________
A metal and a non-metal.
In an ionic lattice, each positive ion is surrounded by _________.
Negative ions,
In an ionic lattice, each negative ion is surrounded by _________.
Positive ions,
What state are Ionic compounds at room temperature?
Solid.
What makes an ionic compound stronger?
A smaller size of ions and a greater charge of the ions.
What is a covalent bond?
The sharing of electrons between two or more non-metals.
What is the Octet rule?
Each atom can only have eight electrons in it’s outer shell.
What is a dative covalent bond?
A bond where the shared pair of electrons has been donated by the same atom.
What are the exceptions to the Octet rule?
An atom could have not enough electrons or more than eight electrons.
What is metallic bonding?
Ordererd positive metal ions surrounded by delocalised electrons.
