Atomic Anatomy
The central part of the atom that holds the protons and neutrons.
What is the nucleus?
Elements in the same vertical column are in the same one of these, meaning they behave similarly.
What is a group (or family)?
Atoms that have gained or lost electrons to achieve a full outer shell.
What are ions?
NaCl
What is Sodium chloride?
Potassium bromide.
What is KBr?
This number at the top of an element's tile tells you the exact amount of protons.
What is the Atomic Number?
This boundary line on the periodic table separates the metals from the non-metals.
What is the staircase, or metalloids?
Metals on the left side of the periodic table generally do this to their electrons to become stable.
What is lose them?
MgO
What is Magnesium oxide?
Sodium hydroxide.
What is NaOH?
In a neutral atom of Sodium, this is the total number of electrons.
What is 11?
The maximum number of electrons that can fit in the third electron shell.
what is 8?
The term for a positively charged ion, formed when an atom loses electrons.
What is a cation?
Na2SO4
What is Sodium sulfate?
Copper(I) oxide.
What is Cu2O?
You calculate this by taking the rounded atomic mass and subtracting the atomic number.
What is the number of neutrons?
The specific technical vocabulary term for an electron located in the outermost shell of an atom.
What is a valence electron?
The final stable ion symbol and charge when a Magnesium atom loses two electrons.
What is Mg2+?
Cu(NO3)2
What is copper(II) nitrate?
Iron(III) sulfate.
Fe2(SO4)3?
The specific number of protons, neutrons, and electrons in an ion of Aluminum.
What are 13 protons, 14 neutrons, and 10 electrons?
The reason why an element like Neon is stable and safe, but pure Sodium metal explodes in water.
What is a full valence shell?
When drawing a Lewis dot diagram for a stable ion form, you must include these two specific things.
What are square brackets and the final charge?
Pb(CO3)2
What is Lead(IV) carbonate?
Tin(IV) phosphate.
What is Sn3(PO4)4?
