structure of the atom

Question 1

do atoms have a charge?

Answer 1

atoms have no overall charge as protons and electrons have the same charge

Question 2

proton

- the location, mass and charge

Answer 2

found in the nucleus
mass of 1
+1 charge

Question 3

neutron

- the location, mass and charge

Answer 3

found in the nucleus
mass of 1
charge of 0
neutron = mass - atomic number

Question 4

electron

- the location, mass and charge

Answer 4

found in the outer shell
mass of 1/1835
charge of -1

Question 5

what’s the mass number:

Answer 5

the number of protons and neutrons in the nucleus

top number -> mass = heavy

Question 6

what’s the atomic number?

Answer 6

the number of protons and electrons

the bottom number -> atoms are light

Question 7

the structure of an atom

Answer 7

small central nucleus made up of protons and neutrons.
electrons orbit (move around) the nucleus in shells.

Question 8

how to find relative atomic mass:

Answer 8

(mass x abundance) + (mass x abundance)
———————————————————————
100

do the percent of 1 x the mass no
then do the same for 2

answer should be in-between the mass numbers of the element
