Conceptual Physics-Atom Minni Unit

Question 0

What/Where are the parts of and atom?

Answer 0

Protons- in nucleus
Neutrons- in nucleus
Electrons- in energy cloud

Question 1

What are the smallest particles that still have all the properties of an element?

Answer 1

Atoms

Question 2

What sub-atomic particle moves easily?

Answer 2

Electron

Question 3

What are the charges of each sub-atomic particle?

Answer 3

Proton- positive
Neutron- neutral
Electron- negative

Question 4

How does an atom become charged?

Answer 4

If it gains electrons- it is negatively charged

If it loses electrons- it is positively charged

Question 5

Why are certain objects attracted to or repelled from each other?

Answer 5

This is caused by the objects’ respective charges: opposites attract; like charges repel.

Question 6

Why can’t protons and neutrons move from atom to atom?

Answer 6

They are tightly bound in the nucleus and they define the element of the atom.

Question 7

A negative atom has more blank than blank.

Answer 7

Electrons, protons

Question 8

A positive atom has more blank than blank.

Answer 8

Protons, electrons

Question 9

If a negative object is repelled from a surface, the surface has what charge?

Answer 9

Negative

Question 11

Two objects are attracted to each other. One is positive. Therefore…

Answer 11

The other object is negative

Question 12

What makes up all matter?

Answer 12

atoms

Question 13

What particles make up atoms?

Answer 13

protons, neutrons and electrons

Question 14

Which sub-atomic particles have charges?

Answer 14

protons (positive)

electrons (negative)

Question 15

Where can electrons be found

Answer 15

in the energy cloud of the atom (flying/orbiting the atom, or moving to another atom)

Question 16

charged particles create what kind of force with other charged particles?

Answer 16

electrostatic

Question 17

neutral charges are blank by other charges.

Answer 17

attracted

Question 18

atoms and molecules are held together by blank.

Answer 18

electrostatic force

Question 19

What are the smallest particles that still have all the properties of an element?

Answer 19

atoms

Question 20

How can an object become electrically charged?

Answer 20

by friction
by conduction
by polarization/induction

Question 21

atom

Answer 21

smallest particle that still has all the properties of a certain element

Question 22

sub-atomic particle

Answer 22

makes up an atom; does not have the qualities of one particular element

Question 23

neutron

Answer 23

sub-atomic particle; neutral (no) charge; located in the nucleus of an atom; does not easily move between atoms

Question 24

electron

Answer 24

sub-atomic particle; negative charge; located in the energy cloud of an atom; easily moves from atom to atom

Question 25

proton

Answer 25

sub-atomic particle; positive charge; located in the nucleus of atom; does not easily move between atoms

Question 26

electrostatic

Answer 26

static electricity, or stationary electric charges, or stationary build up/lack of electrons in an object

Question 27

nucleus

Answer 27

center of an atom where most of the mass (protons and neutrons) is located

Question 28

net charge

Answer 28

overall (total) amount of charges, either positive, negative, or neutral (the later meaning it has no net charge)

Question 29

conduction

Answer 29

when one object touches another (when discussing electrostatic matters, it means the transfer of electrons when two objects touch).

Question 30

attraction

Answer 30

when two or more objects (are compelled to) move towards each other (like when opposite charges are placed next to each other)

Question 31

repulsion

Answer 31

when two or more objects (are compelled to) move away from each other (like when like charges are placed next to each other)

Question 32

element

Answer 32

basic substance that can’t be simplified

Question 33

melecules

Answer 33

two or more atoms that are chemically joined together

Question 34

compound

Answer 34

atoms bonded together that contain at least tow different elements

Question 35

periodic table of elements

Answer 35

a table in which the chemical elements are arranged in order

Question 36

examples of elements

Answer 36

gold, silver, carbon, lead, oxygen, hydrogen

Question 37
