Flashcards in Outcomes 3.4 - 3.6 (Test on Monday, January 25, 2016) Deck (65):
1

What element is a Anion?

 a Non-Metal

2

What is the Symbol for Carbon tetrachloride?

CCl4

They will gain 1 electrons

They wil have a charge of  -1

5

What type of metals in the periodic table of elements are able to form more than one kind of ion?

The transition metals

6

Do metals bond to form a compound?

no

7

How to name Ions when it is a cation?

We use the name of the element, followed by the word "ion" 

Example: Aluminum ion, Magnesium ion, Lithium ion

8

Elements in group 18 will lose/gain howmany electrons? What would their charge be?

They will lose/gain no electrons

They have no charge

9

Elements in group 13 will lose/gain howmany electrons? What would their charge be?

10

What is the goal of each atom in the compound?

Is to fill its valence shell

11

What does the roman numeral at the end of the transition metalès name represent?

Its charge

For Ex;

Nickel III Bromide -- The charge of the nickel is 3+

12

Typically, atoms with this amount of valence electrons will gain electrons?

more than 4 valence electrons

13

What do chemical formulas tell us about?

Chemical formulas tell us the ratio of the number of atoms of each element in a compound. 

14

Compounds often have what properties?

Compounds often have properties that are VERY DIFFRENT from elements they are made of. For example, water is a liquid at room temperature, but its constituents, oxygen and hydrogen, are both gases at room temperature.

15

What is the Anion name of Fluorine?

Fluoride

16

Why does the process of atoms gaining/losing atoms happen?

Because they have a desire to fill their valence shell

17

What is the charge of a Cation?

Positive

18

Cations Lose of Gain electrons?

Lose

19

In the compounds that had ionic bonds, what did you notice about where the metal was in the formula?

The metal is always the first element in the compound

20

How do atoms become ions when they lose or gain electrons?

It happens because the number of positively charged particles (protons) and negatively charged particles (electrons) are NO LONGER EQUAL

21

What happens to Calcium during Ionic bonding? How do we know?

It will lose 2 elctrons while gaing 2 positive charges

Because calcium has 2 valence electrons

22

Elements in group 16 will lose/gain howmany electrons? What would their charge be?

They will gain 2 electrons

They wil have a charge of  -2

23

What are the three ways that elements can obtain a full valence shell?

They can gain valence electrons

They can lose valence electrons

They can share valence electrons

24

What are the two ways that atoms can bond or combine?

Covalently or Ionically

25

How does ionic bonds occur?

They occur when electrons transfer from one atom to another.

26

What happens when atoms gain or lose electrons?

They become ions

27

What element name comes first base on the rules for Covalent compounds?

The elements closest to the upper left hand corner of the non-metals (closest to carbon) comes first.

 

28

Elements in group 1 will lose/gain howmany electrons? What would their charge be?

They will lose 1 electron

They wil have a charge of  +1

29

What are the prefixes base on the rules for Covalent compounds? 1 -10

1 = mono

2 = di

3 = tri

4 = tetra

5 = penta

6 = hexa

7 = hepta

8 = octa

9 = nona

10 = deca

30

What happens to Chlorine during Ionic bonding? How do we know?

It will gain 2 electrons while losing a negative charge

Because calcium has 7 valence electrons

31

32

How are Covalent compounds diffrent to 
Ionic compounds?

Covalent compounds are diffrent to Ionic compounds because where Ionic compiunds lose or gain electrons, in covalent compounds, the electrons are SHARED between atoms

This sharing of elecdtrons IS  the covalent bond

33

How are Covalent Compounds formed? 2

Are formed between elements that are both non-metals.

Covalent compounds are also called molecular compounds

34

If the number of protons is greater than the number of electron, the ion is?

Has a positive charge

35

What type of bond happens when a metal and a non-metal bonds?

an IONIC BOND

36

Elements in group 14 will lose/gain howmany electrons? What would their charge be?

They will gain/lose 4 electrons

They wil have a charge of  +4 0r -4

37

What happens when metals mix together?

if metals mix together, the substance taht is formed is called an alloy

38

What are the transition metals that are exceptions to the rule (Some transition metals have multiple charges) ? 2

Silver(Ag) will always have a plus one charge

Zinc(Zn) will always have a plus 2 charge

39

Are polytomic ions neutrally charged?

40

What is the Anion name of Chlorine?

Chloride

41

What is the number of something in an atom that changes?

Electrons

42

Why don't the names of ionic compounds include prefixes?

For example: Sodium will only bond with chlorine once

43

What do prefixes mean base on the rules for Covalent compounds?


The number of atoms of each element

44

How to name Ions when it is a Anion?

We drop the ending of the element's name and add the suffix "ide"

Example:

Hyrogen = Hydride

Flourine = Fluoride

Oxygen = Oxide

 

45

What is the charge of an Anion?

Negative

46

What type of bond happens when a non-metal and a non-metal bonds?

A COVALENT BOND

47

What is the Anion name of Arsenic?

Arsenide

They will lose 2 electron

They wil have a charge of  +2

51

What are Polytomic Ions? 3

Is a charged particle with more than one atom

They are bonded covalently. and are not neutrally charged

They do not have an equal number of protons and electrons

52

What is the number of what that determines whether the atom will gain or lose electrons?

valence electrons

The second element

61

What is the Anion name of Bromine?

Bromide

62

How do we write Ion Symbols/Formulas?

We write the symbol of the element followed by the charge in superscript.

Never write -1 or +1 just use a "-" or a "+"
