Atomic Structure And Bonding Flashcards
(23 cards)
What is the mass number made of
Number of protons + number of neutrons
What is the atomic number made of
Number of protons
What are ions
A charges particle atoms gain or lose electrons to achieve a stable outer electron arrangement
State the 4 shapes of molecules
Linear
Angular
Pyramidal
Tetrahedral
What’s electrostatic force
Positive nuclei attracted to negative electrons
What rule does the compound with more than two elements follow
Ate/ite
what are full shells said to be
Stable therefore unreactive
If a ion has a positive charge does it gain or lose a electron and if it has a negative
Negative - gain
Positive - lose
What rule does the two element compounds follow
IDE
How many electrons does the first shell hold
Two
If a ion shows a loss where does it appear and a gain
Loss- right
Gain- left
Do covalent substances conduct electricity
They do not conduct electricity any any sate of matter the only exception is carbon in a graphite form
What are diatomic elements
Any molecule made up of only two atoms
Hydrogen
Nitrogen
Fluorine
Oxygen
Iodine
Chlorine
Bromine
What is a ionic bond
A ionic bond is the electrostatic attraction between a positive metal ion and a negative non- metal ion
What is a covalent bond
When two positive nuclei are held together by their common attraction for a shared pair of electrons
What is metallic bonding
Metallic bonding is the attraction between ions and a sea of delocalised negative electrons
Do metallic substances conduct electricity
Yes the conduct in any state of matter
Do ionic substances conduct electricity
They only conduct when in a liquid solution but not in a solid
What is mass of protons, electrons and neutrons
Electrons- 0 amu
Protons- 1 amu
Neutrons- 1 amu
What is the charge of protons,electrons and neutrons
Protons- +1
Electrons- -1
Neutrons- 0
How do get the number of neutrons
Mass number- number of protons
What are isotopes
The same atomic number but different mass number
What is ionic, covalent and metallic
Ionic - nom metal and metal
Covalent - non metals only
Metallic - metals only
