Menentukan jumlah proton, elektron dan neutron

Pembahasan

[tex]\boxed{\boxed{\bold{Lambang~Atom}}}[/tex]

Berdasarkan percobaan yang dilakukan oleh H.Moseley didapatkan hasil percobaan yaitu jumlah proton merupakan sifat khas dari suatu atom. Jumlah proton berbanding lurus dengan besarnya nomor atom. Selanjutnya jumlah proton yang terdapat dalam inti atom disebut dengan nomor atom (Z). Sedangkan nomor massa (A) merupakan jumlah proton dan neutron dari atom.

[tex]_{Z}^{A}\textrm{X}[/tex]

X = lambang unsur

A = nomor massa

Z = nomor atom

p = proton

e = elektron

n = neutron

p = Z

n = A – p

Untuk atom netral

e = p

[tex]\boxed{\boxed{\bold{Jawab}}}[/tex]  

Z = nomor atom

A = nomor massa

p = Z

e = p

n = A - p

====================================

[tex]_{8}^{16}\textrm{O}[/tex]

Z = 8

A = 16

p = Z = 8

e = p = 8

n = A - p = 16 - 8 = 8

====================================

[tex]_{8}^{17}\textrm{O}[/tex]

Z = 8

A = 17

p = Z = 8

e = p = 8

n = A - p = 17 - 8 = 9

====================================

[tex]_{7}^{15}\textrm{O}[/tex]

Z = 7

A = 15

p = Z = 7

e = p = 7

n = A - p = 15 - 7 = 8

====================================

[tex]_{11}^{23}\textrm{Na}[/tex]

Z = 11

A = 23

p = Z = 11

e = p = 11

n = A - p = 23 - 11 = 12

====================================

[tex]_{19}^{29}\textrm{K}[/tex]

Z = 19

A = 29

p = Z = 19

e = p = 19

n = A - p = 29 - 19 = 10
