Atom, Chemical Reactions, Bondings

Question 1

Atom formula (state the variables)

A =
x = 
z =
e- =
(+) =
(-) =
(o) =

Answer 1

A = mass #
x = element symbol
z = atomic #
e- = element (charge)
(+) = protons
(-) = electrons
(o) = neutrons

Question 2

Atom formula

Answer 2

(+) = z = (-)
A = (o) + (+)

[proton = atomic # = electron]
[mass # = neutron + proton]

Question 3

REMEMBER (!!!)

Atom formula for mass/neutrons
A = (+) + (o)

Answer 3

.
