Characteristics of ionic compound names

Front

Cation followed by the anion. If the compound is formed with a transition metal and there are more than one possibleions that can be present.

Back

Isotope

Front

Each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties.

Back

Where are the valence electrons in an atom?

Front

In the outermost occupied shell of an atom.

Back

Elements in group 15 have a

Front

-3 charge

Back

Groups

Front

vertical columns on periodic table

Back

Naming ionic compounds

Front

Identify the cation and anion. Name the cation by its element name. Name the anion by using the first syllable of its element followed by "ide". Write the name of the cation first and the name of the anion second.

Back

Elements in group 3A (aka 13) have a

Front

+3 charge

Back

Elements in group 18 (Noble gases) have a

Front

0 charge

Back

Elements in group one on the periodic table have a

Front

+1 charge

Back

Specific Heat

Front

The amount of heat in calories of Joules that raises the temperature of 1 gram of a substance by 1 degree Celsius.

Back

Positive ions forming

Front

When an element, typically a metal loses 1 or more electrons.

Back

Metals

Front

Shiny and ductile. Good conductors of heat.

Back

Cation

Front

Positively charged ion.

Back

Elements in group 17 have a

Front

-1 charge

Back

Elements in group 16 have a

Front

-2 charge

Back

Charge of Neutrons

Front

neutral

Back

The mass number

Front

Number of protons + number of neutrons.

Back

How do subscripts represent the charge balance of ions?

Front

To balance the charges of ions the number of electrons lost is equal to the number of electrons gained. The overall net charge must be zero. The number of ions needed to accomplish this is represented by the subscripts.

Back

Why are electrons shared in covalent compounds?

Front

Nonmetals tend to have high electronegativity values and thus share electrons rather than lose them. Typically, if a compound has an electronegativiy of less than 1.9 it is a covalent bond.

Back

Negative ions forming

Front

When an element, typically a nonmetal gains 1 or more electrons.

Back

Characteristics of names of covalent Compounds:

Front

Least electronegative ion first and prefixes are given to both ions to indicate the number of atoms in each element present. The second ion ends in "ide"

Back

Charge of proton

Front

Positive

Back

Charge of Electrons

Front

negative

Back

Nonmetals

Front

Dull and brittle. Poor conductors of heat, but good insulators.

Back

Elements in group 4A (aka 14) have a

Front

+4 or -4 charge

Back

Nucleus

Front

Contains protons and neutrons and is surrounded by electrons.

Back

The atomic number

Front

Number of protons (and number of electrons)

Back

Periods

Front

horizontal columns on periodic table

Back

Anion

Front

Negatively charged ion.

Back

Metalloids

Front

Semiconductors and insulators.

Back

Elements in group 2 on the periodic table have a

Front

+2 charge
