Structure And Bonding Flashcards
1
Q
What does an atom comprise of?
A
Sub atomic particles Protons = mass of 1, charge of +1 Neutrons = mass of 1, charge of 0 Electrons = mass of almost zero, charge of -1 Nucleus = tiny but heavy
2
Q
What is the rule of atoms?
A
All atoms are neutral
Number of protons = number of electrons
3
Q
What is the mass number equal to?
A
Number of protons + number of neutrons
4
Q
What is the atomic number equal to?
A
Number of protons = number of electrons
5
Q
How do you work out the number of neutrons?
A
Mass number - atomic number
