History of the Periodic Table
He is considered the "father" of the periodic table.
Who is Mendeleev?
They are the first group on the periodic table.
What are the alkali metals?
This type of ion is produced when a stable atom loses an electron.
What is a cation?
Atomic radius tends to do this when moving across a period.
What is decrease?
Elements are more stable and unreactive when they have this.
What is a full octet?
This can be defined as the tendency to recur at regular intervals.
What is periodicity?
The elements located in this group are inert because of their fully formed octet.
What is group 18?
This can be defined as the measure of the ability of an atom in a chemical compound to attract electrons from another atom in the compound.
What is electronegativity?
This proccess causes ionization energy to decrease down a group because it results in the nucleus retaining less of a hold on the outer electrons.
What is sheilding?
This group configuration represents group 2 on the periodic table.
What is ns2?
These are consistent when elements are organized by atomic number.
What are the properties?
This block of the periodic table was the last to be added and consists of the inner-transition metals.
What is the f block?
If Chlorine were to gain and electron it would be called this type of ion.
What is an anion?
This endothermic reaction tends to increase across a period.
What is ionization energy?
To determine the amount of valence electrons in an element in the p block, one should use this number.
What is the group number minus 10?
All of the noble gasses were discovered by William Ramsay except for this one, which was discovered by German scientist Freidrich Dorn.
What is Radon?
These types of metals are found in the d block.
What are the transition metals?
In electron affinity, sometimes an element does not want an electron so much that energy needs to be given. When that scenario takes place this is the value given to represent the electron affinity for that element.
What is 0?
When dealing with ionization energy, more energy is always required when multiple of these are extracted.
What are electrons?
Although this element's configuration follows the group configuration for group 2, it is a part of group 18.
What is Helium?
Stanislao Cannizzaro presented a method for creating standard values for atomic mass at this conference.
What is the First International Congress of Chemists?
The elements in this group are more likely to become anions.
What are the halogens (or group 17)?
These types of atoms have the same electron configuration despite being different elements.
What is isoelectronic?
Elements with the most metalic characterisitics are found in this corner of the periodic table.
What is the bottom left corner?
The periodic table is aranged in order of this.
What is atomic number?
