This is the number listed in the box on the periodic table that tells you how many protons the atom has.
What is the atomic number?
100
The periodic trend in atomic size depends on the nuclear charge (# of protons in the nucleus) and this factor that describes how outer electrons feel less of the nuclear charge because inner electrons block them from it.
What is shielding?
100
This suffix is used to show that a polyatomic ion contains oxygen and could also be used to suggest that you are no longer hungry.
What is -ate?
100
This broad category of elements will all tend to lose electrons when they become charged.
What are metals?
200
Hey, why don't we fill this football with helium and see how far we can kick it!
What is an experiment?
200
The mass number results from the addition of these subatomic particles that give the atom its mass.
What are protons and neutrons?
200
This property of atoms is the energy required to remove electrons from its outer shell. Its easier for larger atoms where those electrons are further away from the nucleus.
What is ionization energy?
200
While cations retain their element name in a compound, the anions will drop the last syllable in lieu of this suffix.
What is -ide?
200
Nonmetals will gain electrons to complete their energy level according to this rule.
What is the octet rule?
300
Hey bro, I think if you studied, like at all, then you might have had a chance at passing this course.
What is a hypothesis?
300
These types of subatomic particles will always be equal if the atom is in its neutral state.
What are protons and electrons?
300
This happens to the size of cations as you move left to right across the period.
What is decrease?
300
Prefixes that denote the number of species present can be used for these types of componds but never for ionic ones.
What is covelant (molecular)?
300
These are the only electrons that can be gained or lost from an atom.
What are valence electrons?
400
"The Bro Code" #7. A bro never sends a greeting card to another bro. There are no sentiments between two bros that cannot be articulated through the convenience and emotional distance of electronic mail.
What is Scientific Law?
400
These occur when atoms of the same element have different numbers of neutrons.
What are isotopes?
400
This is the most electronegative element due to its combination of small size (allows other atoms to get close to its nucleus) and shortage of electrons (it only needs 1 more!).
What is fluorine?
400
We use these to show the charge of a transition metal when naming because its not as easy to tell the charge on them as it is other metals.
What are roman numerals?
400
Atoms within this group do not typically form ionic compounds because it's very hard for them to gain or lose that many electrons.
What is group 4?
500
From what I have seen numerous times before, Nicholas Sparks could describe the gagging smell of rotting human flesh and women would think it was the most romantic thing ever!
What is a theory?
500
This value, unique to every atom, is derived from the weighted average of the atom's isotopes based on their relative abundance.
What is atomic mass?
500
Metals would tend to have low values for this property because they do not want to get more electrons, in fact, they would rather get rid of some of the ones they have.
What is electron affinity?
500
Polyatomic ions containing oxygen that have an -ite suffix generally have this many oxygen atoms relative to the same ion with an -ate suffix.
What is one less?
500
Cations and anions combine in specific ratios to form ionic compounds with this charge.
