Chapter 10 Quiz

Tell me if anything is wrong. Yk the usual fun stuff, everything came from Mr. F's notes plus the book. heres my notes if ya wanna see (book notes + mr. f) Lesson 3: https://docs.google.com/document/d/1xz5j6CJO-LaZvRcil7SQmYY_WGZfQ8_yKJHFayxz5oQ/edit?pli=1# Lessons 1 and 2: https://docs.google.com/document/d/1QYHOAzaFjQxSMQYALRwIcz1yO_De-vKJLgAXeaduMik/edit#heading=h.m9gdb6sgs64i C:

Nonmetal

Elements that have no metallic properties.

Where are non metals located on the table?

right of staircase (and hydrogen)

T or F: Many nonmetals are vital for keeping you alive.

true

What are the properties of nonmetals?

opposite of metals. Dull, not malleable, not ductile, poor conductors of heat and electricity.

Most nonmetals are in which state? (Room temp.)

Solid (thats what google says)

If a nonmetal is solid it has a \_____________ surface.

dull.

Metalloids

Elements that have properties of both metals and nonmetals.

Where are metalloids located on the periodic table?

staircase between metals and nonmetals.

What elements make up the metalloids? (if the staircase thingy doesn’t help).

B, Si, Ge, As, Sb, Te, Po, At

Metalloids are \_____________.

semiconductors

semiconductor

A substance that can conduct electricity under some conditions. High temperatures: Yes. Low temperatures: no.

Silicon, a Metalloid, is used to create computer chips because it is a semiconductor. (True or false).

True

Halogens

an element that can react with a metal and form a salt.

Are all halogens nonmetals?

everyone, except astatine

How many valence electrons do halogens have?

7

Does reactivity increase or decrease as you go down the Halogens?

decrease, fluorine is the most reactive.

Hlogens only occur naturally in \_____________.

compounds

Because Halogens have 7 shells they can. . .

easily gain a full outer shell by gaining 1 electron

Noble Gases are located where?

All the way on the right. Group 18.

All noble gases are

nonmetals

The each have \_____ valence electrons.

8

Because noble gases have a full outer shell, they are considered \_____?

inert, unreactive.

Noble Gases only form __________ under certain conditions. ( not in nature).

compounds.

What is a group?

A column on the periodic table. ↓ (Vertical)

Groups are organized by...

number of valence electrons. Meaning each group has the same number of valence electrons.

Periods are organized by

increasing atomic number

What is peroid?

the rows on the periodic table. → (Horizontal)

Luster

the ability of a metal to reflect light.

Ductility

the ability of a substance to be drawn, pulled, or extruded through a small opening to produce a wire

Malleability

the ability of a substance to be hammered or beaten into thin sheets

Oxidation/Oxides

reacting with oxygen. Oxidation makes oxides. (platinum metals do not react to oxygen).

catalyst

substance that speeds up the rate of a chemical reaction

Where are the transition metals located?

groups 3-12. and the Actinide and Lanthanide series.

All transition elements are

metals

Uses of transition metals

they are strong and used for building (industrial applications). Jewelry (luster), wires (conductivity),

How did Mendeleev organize his periodic table?

Mendeleev arranged the elements in his periodic table in order of increasing atomic mass

Valence electrons are on the \________ shell.

outer

Alkali metals are located where?

group 1.

Alkali metals do not include \__________.

Hydorgen

What are the properties of Alkali metals?

-React quick with other elements, like oxygen
-occur in nature in compounds.
-have a silvery appearance
-soft (enough to cut with a knife.)
-Lowest density of metals.

Alkaline metals are where?

group 2.

Alkaline metals properties:

- react fast, but not as fast as Alkali.
-only occur in compounds.
-soft and silvery (like alkali).
-have low density (but not as low as Alkali)

Why were the lanthanides & actinides removed from the main body of the periodic table?

because they would make the table to wide

What are some patterns you see in the periodic table? (I doubt I listed all of them. I tried).

-Generally, elements increase in metallic properties (Luster, malleability, and electrical conductivity) as you go from right to left. (

CONNECT: Without actually seeing the elements themselves, what can you infer about the element Se (selenium)?

Atomic number 34 and an atomic mass of 78.96. Nonmetal so, dull not malleable, ductile or conductive. Probably a gas or solid.

CONNECT: Without actually seeing the elements themselves, what can you infer about the element Zn (Zinc)?

\
(Try these on your own just chose a random element and write ur answer and then google it. Ta-da. Im so smart c: ).

Its a transition metal so, Zn is strong, malleable, ductile, conducts, has luster. Has 30 protons, Atomic mass is 66.37 (around).

Metals are

Malleable, ductile and good conductors of heat and electricity. Have luster

GOOD LUCK

thanks.
