This element is the most common in the universe and has one valence electron.
Hydrogen
Elements of this family were among the last discovered because they are inert, having a full valence shell.
Noble gases
A positively charged ion
Cation
This bond forms typically forms between metals and non-metals.
Ionic bond
As a general trend, atomic radius increases toward this corner of the periodic table.
Lower left
Found in toothpaste, this element is the most reactive of all elements and has 7 valence electrons.
Flourine
Elements of this family are used to harden teeth, sanitize drinking and swimming water and have 7 valence electrons.
Halogens
A negatively charged ion
Anion
Electrons are shared between atoms like a basketball being shared by two players in a game of P I G.
Covalent bond
The reactivity of metals increases toward this corner of the periodic table.
Lower left
Named after coal, this element has 4 valence electrons and forms millions of compounds that are key to living organisms.
Carbon
Elements of this family are the most reactive metals, and form ions with a 1+ charge.
Alkali Metals
Metals in Group 2 will form ions having a charge of...
2+
The strongest type of bond and is the result of two different types of ions being attracted to each other.
Ionic bond
With the exception of the noble gases, the reactivity of non-metals increases toward this corner.
Upper right
This element has 5 valence electrons and makes up about 78% of the atmosphere.
Nitrogen
Elements of this family are in more than one group, are NOT shiny, and do NOT conduct electricity.
Other non-metals
Oxygen, having six valence electrons, will form an oxide ion having a charge of...
2-
The valence electrons are delocalized, forming a sea of electrons moving around many positively-charged atoms.
Metallic bond
Mendeleev was not the first to make a type of periodic table, but he was the first to...
make predictions from it.
This element has 1 valence electron, floats in water, and is used in medicine to treat mental illness.
Lithium
Some elements of this family can form up to 4 different cations because of the different kind of electron configuration they have. They are shiny and good conductors of heat and electricity.
Transition Metals
If oxygen (group 16) and sodium (group 1) bond, there will be ______ sodium atoms per 1 oxygen atom.
2
Valence electrons are shared, but not equally, creating a positive pole and a negative pole in the compound.
Polar covalent bond
The periodic table is arranged according to atomic number and ...
