<p>Ionic compounds</p>

Ionic compounds

composed of positively and negatively charged ions held together by strong electrostatic forces. Result from the transfer of electrons from one element to another.

2 methods for naming cations of metals that form 2 different cations

Systematic Method: follow the name of the cation by a Roman numeral in parentheses to indicate its charge -or- Common Method: Use the suffix -ous for the cation with the smaller charge, and the suffix -ic for the cation with the higher charge. These suffixes are often added to the Latin names of the elements

6
New cards

Variable charges of Fe

Fe²⁺, Fe³⁺

7
New cards

ion found in hemoglobin

Fe²⁺

8
New cards

fixed charge of Co

Co²⁺

9
New cards

fixed charge of Al

Al³⁺

10
New cards

Variable charges of Cu

Cu⁺, Cu²⁺

11
New cards

Fixed charge of Zn

Zn²⁺

12
New cards

anions

newly updated

13
New cards

Variable charges of Sn

Sn²⁺, Sn⁴⁺

14
New cards

types of elements that form ionic bonds

ionic bonds are formed between a metal on the left side of the periodic table and a nonmetal on the right side

15
New cards

cations

positively charged ions. A cation has fewer electrons than protons. Cations are formed by metals.

  • for metals in groups 1A, 2A, and 3A, the group number = the charge on the cation

16
New cards
<p>Covalent compounds</p>

Covalent compounds

composed of individual molecules, discrete groups of atoms that share electrons. Result from the sharing of electrons between two atoms

17
New cards

Fixed charge of Ni

Ni²⁺

18
New cards

3 steps to derive a formula from the name of an ionic compound

  1. identify the cation and anion and determine their charges

  2. Balance the charges of the ions

  3. Write the formula with the cation first, and use subscripts to show the number of each ion needed to have zero overall charge

19
New cards

How to name anions

Replace the ending of the element name by the suffix -ide

20
New cards

general rule about boiling points and melting points of ionic compounds

They are extremely high because of the strong electrostatic bonds.

21
New cards

Variable charges of Au

Au⁺, Au³⁺

22
New cards

Variable charges of Pb

Pb²⁺, Pb⁴⁺

23
New cards

5 physical properties of ionic compounds

  • high melting points

  • high boiling points

  • usually soluble in water

  • their solutions conduct electricity

    • they form crystalline solids

24
New cards

ion needed for nerve transmission and muscle control

25
New cards

polyatomic ion

a cation or anion that contains more than one atom

26
New cards

fixed charge of Mn

Mn²⁺

27
New cards

formula for hydronium ion

formula for sulfate ion

SO₄²⁻

32
New cards

formula for phosphate

PO₄³⁻

33
New cards

Fixed charge of Ag

Ag⁺

34
New cards

when to use suffix -ite

used for an anion that has one fewer oxygen atoms than a similar anion named with the -ate ending (ie. SO₄²⁻ is sulfate, but SO₃²⁻ is sulfite)

35
New cards

How to name anions that differ in presence of hydrogen

the word hydrogen or prefix bi- is added to the name of the anion. (ie. SO₄²⁻ is sulfate, but HSO₄⁻ is hydrogen sulfate or bisulfate)

New cards

3 steps to write a formula for an ionic compound

  1. identify which element is the cation and which is the anion (use the group number of a main group element to determine the charge)

  2. Determine how many of each ion type is needed for an overall charge of zero.

    1. To write the formula, place the cation first and then the anion, and omit charges. (Use subscripts to show the number of each ion needed to have zero overall charge)
