Atomic Structure And Bonding Flashcards
Where are protons found?
In the nucleus of an atom.
Where are neutrons found?
In the nucleus of an atom.
Where are electrons found?
In shells around the nucleus.
What is the relative mass of a proton?
1
What is the relative mass of a neutron?
1
What is the relative mass of an electron?
1/1840
What is the relative charge of a proton?
+1
What is the relative charge of a neutron?
0
What is an atom?
The smallest part of an element and is neutral.
What is an ion?
A charged particle with one or more atoms, with the same number of protons and different number of electrons.
If there are more electrons than protons, what is the charge?
Negative, -ve
What is the relative charge of an electron?
-1
If there are more protons than electrons, what is the charge?
Positive, +ve
What is electron configuration?
The number of electrons in an atoms shells. 2.8.8.18
What is ionic bonding?
An electrostatic attraction between oppositely charged ions.
What is a compound?
Two or more atoms chemically bonded in fixed proportions.
What do ionic bonds occur between?
Metals and non-metals.
What do covalent bonds occur between?
Two or more non-metals.
What are covalent bonds?
Sharing electrons between two atoms for both to achieve a full outer shell.
What are the number of covalent bonds an atom can make?
How many electrons are needed to make a full shell.
What is a molecule?
Two or more atoms bonded together through sharing electrons, that are neutral.
