Its Trending
This scientists were the first to come up with a way to arrange the elements on the periodic table
Who is Dmitri Mendeleev?
This best describes the general trend that atomic radius follows on the periodic table.
What is it decreases as you move right in a period and increases as you move down a group?
The amount of energy required to remove a mole of electrons from a mole of gaseous elements
What is the ionization energy
This particle is responsible for chemical bonding.
What is the electron?
The oxides in period 3 which produce basic solutions?
What is Na2O and MgO?
The element with the highest melting point in period 3
What is Si?
Two or more ions that have the same electron configuration are said to be this
What is isoelectronic?
These elements have the highest ionization energies.
What are the Noble gases?
The product of the reaction between K metal and Cl2 gas
What is KCl?
The oxides in period 3 which are amphoteric?
What is Al2O3?
This property was first used to arrange the Periodic Table of the elements
What is the atomic mass?
This particular property of elements can be used to explain why cations get smaller when they form ions and why anions are larger when they form ions.
What is the effective nuclear charge?
The number of valence electrons a third period atom has with the following successive ionization energies
1st 2nd 3rd 4th 5th
738 1451 7733 10540 13628
What are 2 valence electrons?
The product of the reaction between Na2O and water
These oxides of the period 3 elements produces acids in water
What are P4O10, P4O6, SO3, SO2, Cl2O7 and Cl2O
The element in between O and K that has the highest electronegativity
What is O?
Magnesium ion is smaller than Calcium ion for this reason
What is having more occupied energy levels?
As we move up a group on the periodic table the ionization energy increases for this reason
What is decreasing number of occupied energy levels?
The product of the reaction between SO3(g) and water
What is H2SO4?
The product of the reaction between P4O10 and water?
What is H3PO4?
The reason the Si4+ has a smaller radius than P3-
What is fewer occupied energy levels?
Please arrange the following elements based on increasing ionic size: Strontium Ion, Bromide, Selenide, and Rubidium Ion.
What is Sr 2+, Rb 1+, Br 1-, and Se 2-?
Please arrange the following elements based on decreasing ionization energy: Gallium, Krypton, Calcium and Arsenic
What are Krypton, Arsenic, Calcium, and Gallium?
The product of the reaction between F2(g) and Br-(aq)?
What is Br2(l) and F-(aq)?
The product of the reaction between Cl2O7 and water
What is HClO4?
