chemistry 10 Flashcards
what is a valence electron?
The electrons in the outer shell
How do we draw the lewis dot structure?
The last shell of a bohr diagram
What is a covalent bond?
molecule formed when two or more diffrent atoms are connected with a covalent bond
What is a molecular bond?
chemical compound made up of 2 or more nonmetal atoms held together by compound bonds
What is an ionic compound?
Compounds made up of ions charged particles when an atom gains or loses electrons
how do we name ionic compounds?
cation first, anion last
What makes something an acid?
can give hydrogen to another substance
how are naming for binary and ternary acids different?
number of elements they contain
how do we name covalent compounds?
name first element then but ide at the end of the second element
example of ionic compound with a multivalent metal
iron (iii) nitride: FeN
example of molecular compound
H2O= water
what are the 5 types of chemical reactions
combination or synthesis
decomposition
combustion
single displacement
double displacement
example of combination reaction
hydrogen + nitrogen = ammonia
example of decomposition reaction
CO= C+O
example of combustion reaction
carbon + oxygen + carbon dioxide
Example of single displacement reaction
K + NaCl=KCl+ Na
Example of double displacement reaction
AgNO3+NaCl=AgCl+NaNo3
what makes something an acid
Acid produces hydrogen ions in solution
What makes something a base
substance that produces Hydroxide ions in solution
how is water related
water accepts hydrogen ions when mixed with acid. when water mixes with a base the base donated hydrogen atoms and acts like an acid
how can you tell how acidic/basic something is
the Ph levels
what is one you can make at home
boiling red cabbage
what scale do we use to measure acidity
The PH scale
what is neutral
Ph of 7
