6A Elements And The Periodic Table (Interactive Science)

Front 1

How was Mendeleev's

periodic table arranged?

Back 1

By increasing atomic mass

Front 2

What are the two most

common alkaline

earth metals?

Back 2

Calcium and Magnesium

Front 3

More than half of of the

nonmetals are __________

at room temperature.

Back 3

gases

Front 4

Bohr's Model

Back 4

A model whose electron

orbits look like planets

orbiting the sun or layers

of an onion.

Front 5

Family or group

Back 5

A column of elements

in the periodic table.

Front 6

What does the atomic

number of an element

stand for?

Back 6

The number of protons

in the nucleus.

Front 7

What are beta radiation

particles identical to?

Back 7

Electrons

Front 8

What are Isotopes?

Back 8

Atoms with the same

number of protons, but

different numbers

of neutrons.

Front 9

What can you predict

from an element's

location on the

periodic table?

Back 9

The element's properties

Front 10

What elements generally

do not form compounds?

Back 10

The noble gases

Front 11

Name two ways that

protons and neutrons

are alike?

Back 11

They have about the same

mass and both are found

in the nucleus.

Front 12

What are three

properties of metals?

Back 12

Metals are malleable,

ductile, and can carry

an electric current.

Front 13

What are models?

Back 13

Representations of an

idea to help scientists

understand what they

cannot directly observe.

Front 14

Chemical Symbol

Back 14

A one or two letter

representation of

an element.

Front 15

Conductivity

Back 15

To easily transmit

electricity and heat.

Front 16

Radioactivity

Back 16

The spontaneous emission

of radiation by an unstable atomic nucleus.

Front 17

Periods

Back 17

The horizontal rows in

a periodic table.

Front 18

On what side of the

periodic table are the

nonmetals located?

Back 18

The right side of the

periodic table.

Front 19

What is used to organize

the modern periodic table?

Back 19

The atomic number

Front 20

Why is the mass of an

electron not used in

determining the mass

of an atom?

Back 20

The mass of an electron

is lower than the mass

of a proton or neutron and

will not make a big enough

difference to the total mass.

Front 21

How can an atom have

no charge when it is made

of protons, neutrons

and electrons?

Back 21

If an atom has the same

number of protons and

electrons; the negative

and positive charges

balance out and neutrons

have no charge.

Front 22

Why is it not necessary

for electrons to be included

in determining the mass?

Back 22

Since the mass of an electron

is smaller than protons or

neutrons it will not add

enough to the total mass

to make a difference.
