C2 Atomic Structure Flashcards
A carbon atom has 6 protons how many electrons will it have?
6
What is the charge on a proton?
+1
What is a compound?
Substance containing 2 or more elements chemically bonded together
Draw the electron structure of a Lithium atom.
How do you calculate the number of protons in an element?
Atomic number
What subatomic particles are in the nucleus in an atom?
Protons and neutrons
What subatomic particle goes around the nucleus in an atom?
Electrons
How do you calculate the number of neutrons in Lithium?
Mass number- atomic number = 7-3=4
What is the charge on an electron?
-1
What is the relative mass of a proton?
1
How many electrons has Lithium?
3
What is the mass number?
Number of protons and neutrons
How many outer electrons have the elements in group 6?

1/1840
What is the charge on a neutron?
0
How many outer electrons have the elements in group 1?
1
What order are the elements in the modern periodic table?
Atomic number
What is an atom of the same element with a different number of neutrons?
isotope
What is the relative mass of a neutron?
1
How many electrons can occupy the first (inner) shell?
2
Do you always get the same number of protons in an element?
Yes
What happens to electrons when they are involved in bonding?
Transferred or shared
Do atoms have a charge, why?
No because the number of positive protons equal the number if negative electrons
Which electrons are involved in chemical bonding?
Outer electrons
How many electrons can occupy the third shell?
8
