🍄 The Structure of An Atom 🍄

Question 1

what do atoms consist of?

Answer 1

protons, neutrons and electrons

Question 2

what are protons, neutrons and electrons collectively called

Answer 2

sub-atomic particles

Question 3

proton’s type of charge

Answer 3

protons are positively charged

Question 4

electron’s type of charge

Answer 4

electrons are negatively charged

Question 5

neutrons type of charge

Answer 5

neutrons are neutral, meaning they have no charge

Question 6

what is at the centre of every atom?

Answer 6

the Nucleus

Question 7

what does the nucleus contain?

Answer 7

the nucleus contains an equal number of positively charged protons and neutral neutrons

Question 8

a nucleus’ overall type of charge

Answer 8

an overall positive charge

Question 9

why are electrons and protons attracted to one another?

Answer 9

because of their opposite charges

Question 10

what holds the atom together?

Answer 10

the electrical attraction

Question 11

how does an atom become neutral/uncharged?

Answer 11

as the protons and electrons carry an equal-sized but opposite charge, the entire atom is uncharged/neutral

Question 12

what happens if an atom loses or gains electrons?

Answer 12

it becomes charged

Question 13

what if there are more electrons than protons?

Answer 13

if there are more electrons than protons the atom is negatively charged

Question 14

what if there are more protons than electrons?

Answer 14

if there are more protons than electrons the atom is positively charged

Question 15

how are the electrons in an atom found?

Answer 15

the electrons in an atom are found moving rapidly in circular orbits around the nucleus

Question 16

properties of orbits

Answer 16

the orbits are found at fixed distances from the nucleus

Question 17

what are orbits also known as?

Answer 17

energy levels

Question 18

what happens as the further an orbit is away from the nucleus?

Answer 18

as the further an orbit is away from the nucleus, the more energy the electrons in that orbit contain

Question 19

what are the energy levels also known as

Answer 19

energy levels are also sometimes called ‘shells’

Question 20

number of electrons in the 1st shell

Answer 20

2

Question 21

number of electrons in the 2nd shell

Answer 21

8

Question 22

number of electrons in the 3rd shell

Answer 22

8

Question 23

atoms that lose electrons become _________ charged

Answer 23

positively

Question 24

atoms that gain electrons become _________ charged

Answer 24

negatively

Question 25

what are charged atoms called?

Answer 25

Ions
