What are 16 protons and 18 electrons?
This is the name of MgI2
What is magnesium iodide?
This subatomic particle is responsible for determining the identity of the isotope of an atom.
What is the neutron?
This subatomic particle is responsible for determining the identity of the atom.
What is the proton?
This is the name of the rows of the periodic table and how they are organized.
What are periods and by increasing atomic number?
The name and charge of an atom or group of neutral atoms that have gained electrons.
What are anions and negatively charged?
This is the formula of calcium fluoride.
What is CaF2?
This is the isotope name for the isotope with 12 protons and 13 neutrons.
What is magnesium-25?
When graphing, this goes on the x-axis.
What is the independent variable?
This is the name of the columns in the periodic table and how they are organized.
What are groups (or families) and by similar physical and chemical properties?
This subatomic particle is responsible for the properties of bonding.
What are electrons?
This is when you need to use roman numerals in naming ionic compounds.
What is when the metal ion forms more than one possible charge?
This is the number of protons and neutrons present in the following isotope: carbon-14
What are six protons and eight neutrons?
Elemental nickel is white to light grey in color, highly ductile, lustrous, and resistant to tarnish. Pt is likely to share the properties. This is the explanation.
What is because they are in the same family?
This is the estimated melting point of selenium given the melting points of sulfur (115 oC) and tellurium (450 oC).
What is 282.5 oC?
This is the number of protons and electrons in Ag+

This is the formula for iron (III) oxide.
What is Fe2O3?
This is how you determine the mass number in an atom.
What is #p+ + #n0 ?
This is how you determine whether a compound is ionic or molecular.
What is look at the elements present, an ionic compound has a metal or NH4+ ?
This is how Ga and P would react given Al and N form AlN.
What is GaP?
These are the three subatomic parts of the atom and their charges.
What are positive protons, neutral neutrons, and negative electrons?
This is the name of Cr3N2
What is chromium (II) nitride?
This is the symbol for an atom with 7 protons, 8 neutrons, and 7 electrons.
What is
15/(7) N
?
This is the trend in atomic radius as you go left to right across a period and top to bottom down a group.
What is decreasing across a period and increasing down a family?
