Flashcards in 5.3 + 5.4 + 5.5 Deck (22):
1

How many ions do transition metals form?

2 or more (this includes the metals below the later in group 14)
exception: Zn2+, Cd2+, Ag+ (these elements only have one ion)

2

what do roman numerals represent in ionic compounds?

a transition elements' charge

3

polyatomic ions

group of covalently bonded atoms with an overall ionic charge

4

if you add an "H" in front of a polyatomic atom, what is its' naming rule?

you add "bi" in front
eg. HSO3- bisulfite

5

polyatomic atoms end in:

-ate

6

what is the indication that there is one less oxygen than the "-ate" form?

-ite

7

covalent bonds

nonmetals share electrons to form an octet

8

Formation of H2
What happens when a H atom gets closer to another H atom? What kind of bond forms?

attraction increases as they get closer
they form a covalent bond (share electrons)

9

what kind of bonds do diatomic molecules contain?

covalent

10

What are the 7 diatomic molecules?

Hydrogen, Nitrogen, Fluorine, Oxygen, Iodine, Chlorine, Bromine

11

How do you know the number of covalent bond an atom forms?

It usually forms as many it need to form have an octet

12

what is the indication that there is one more oxygen than the "-ate" form?

per-

13

what is the indication that there is two less oxygen than the "-ate" form/one less oxygen than the "-ite" form?

hypo-

14

What are some elements that doesnt follow the octet rule
(2,3,4,10,12,14)

H- 2 electrons
B- 3 electrons
Be- 4 electrons
P- 10 electrons
S- 12 electrons
Cl,Br,I- 14 electrons

15

molecule

2 or more atoms that share electrons

16

single bond

one pair of electrons are shared

17

double bond

two pairs of electrons are shared

18

triple bond

three pairs of electrons are shared

19

resonance structures

two or more electron dot arrangement for a formula

20

how do you show that two or more resonance structures are related?

a double headed arrow

21

what is another word for "shared electrons?"

bonding pair

22

lone pair

non binding pairs of electrons
