Section 1
Valence
What are the electrons that have the highest energy level and are held most loosely?
The chemical bond formed when two atoms share electrons
What is a covalent bond?
an atom or a group of atoms that has an electric charge
What are ions?
Valence electrons range from this to this
?
Name at least 2 properties of metals
What are luster and heat conductivity?
Force of attraction that holds two atoms together
What are chemical bonds?
A neutral group of atoms joined by a covalent bond
What is a molecule?
Symbol for an element surrounded by dots which represent valence electrons
What is an electron dot diagram?
they form as the result of the attraction between positive and negative ions
Why do ionic bonds form?
one shares electrons equally, one doesn’t
What is the difference between polar and nonpolar bonds?
Hydrogen is found in this group
What is group 1?
2 atoms that share 2 pairs of electrons
What is a double bond?
It is because all have the same number of valences electrons in their atoms
Why do elements in the same group have similar properties?
It is the attraction of each atom's nucleus for the shared pair of electrons.
What holds atoms together in a covalent bond?
a chemical bond formed when two atoms share electrons
What is a covalent bond?
Hydrogen is in group one because of this
It has one valence electron?
A bond in which electrons are shared unequally
What is a polar bond?
Atoms that share 3 pairs of electrons
What is a triple bond?
At least one of the elements is a metal
What has to be in every alloy?
the ratio of elements in the compound
What is a subscript?
This gives you information about the arrangement of electrons in atoms.
What is the periodic table?
A bond in which the electrons are shared equally
What is a non-polar bond?
It is made of more that one atom
What is a polyatomic atom?
What is the bunny's real name?
force of attraction that holds 2 atoms together as a result of rearrangement
What is a chemical bond?
