Chapter 6 Vocabulary

Question 1

covalent

Answer 1

relating to or denoting chemical bonds formed by the sharing of electrons between atoms

Question 2

covalent compound

Answer 2

when a molecule is formed from a covalent bond. these covalent bonds results from sharing valence electrons between two atoms

Question 3

formula unit

Answer 3

the smallest combination of atoms or ions that correctly represents the ratio in which they are combined in a chemical compound

Question 4

organic compound

Answer 4

a compound that is built of atoms of carbon

and other elements.

if there is no carbon present the compound is inorganic

Question 5

binary compound

Answer 5

ionic or covalent compound that is made of atoms of two different elements

Ex: MgCl₂

Question 6

diatomic molecule

Answer 6

a molecule that is built of exactly two atoms

either of the same element or two different elements

Question 7

monatomic ion

Answer 7

A single atom

that lost or gained

one or more electrons

as compared to the neutral atom

of the same element.

positively or negatively charged

Question 8

polyatomic Ion

Answer 8

A group of atoms

of the same or different element

held together by covalent bonds

carrying non zero electric charge,

positive or negative.

not a compound per se but

can be part of an ionic compund when combined with an ion of opposite charge

Question 9

ion

Answer 9

refers to the ratio between

protons and electrons in an atom or molecule,

or net electric charge

due to the loss or gain

of one or more electrons

Question 10

acid

Answer 10

a covalent compund whose molecules have a special hydrogen atom

that can be detatched from the rest of the molecule as hydrogen ion ( H⁺ )

in an aqueous solution, water solvent.

The rest of the molecule becomes a negitively charged ion.

A pure acid may not conduct electricity,

but its aqueous solution (acid mixed with water) does conduct electricity.

The sour taste of acids is due to hydrogen ion.
