These flashcards cover key terms and concepts related to atomic structure and the periodic table, assisting students in exam preparation.
Atomic number
The number of protons in an atom, which determines the element's identity.
Atomic Number
Equals the number of protons in the atom.
Atomic Mass
Equals the total number of protons and neutrons (the subatomic particles within the nucleus).
Elements are ordered on the Periodic Table based on this
number of protons
On the Periodic Table, where do you find the number of Protons?
Top number, the atomic number
On the Periodic Table, where do you find the number of Electrons?
Top number, the atomic number
On the Periodic Table, where do you find the number of Neutrons?
You take the bottom number (atomic mass) minus the top number (atomic number)
On the Periodic Table, where do you find the symbol?
The symbol is the letters that stand for the element
On the Periodic Table, what are the Groups?
The groups are the columns
On the Periodic Table, what are the Periods?
