Y9 Atoms Flashcards
What is the relative charge of a proton?
Plus 1 (positive).
What is the relative charge of an electron?
Minus 1 (negative).
What is the relative charge of a neutron?
0 (no charge).
What is the relative mass of a proton?
1.
What is the relative mass of an electron?
1/1835.
What is the relative mass of a neutron.
1.
What is the mass number?
It is the number of protons and neutrons in an atom.
What is atomic number?
It is the amount of protons in an atom (the number of protons is equal to the number of electrons).
What are protons, electrons and neutrons called?
Particles.
Where are protons located?
In the atom’s nucleus.
Where are electrons located?
Orbiting the atom’s nucleus.
Where are neutrons located?
In the atom’s nucleus.
What is electronic structure?
It is the amount of shells and electrons an atom has.
What is maximum amount of electrons that the inner shell can hold?
2.
Wha is the maximum amount of electrons that the 2nd and 3rd shell can hold?
8.
How are ions formed?
They are formed when an atom loses or gains electrons.
What is ionic bonding?
It is when a metal atom donates electrons to a non-metal.
Why does ionic bonding occur?
It occurs because the two atoms are trying to get an full outer shell.
What does ionic bonding form?
Ions.
What is covalent bonding?
It is when two atoms form together.
Why does covalent bonding occur?
It occurs because the two atoms are trying to get a full outer shell.
