Answer 1

b

Answer 2

atomic weight is defined as?

Answer 3

ithink b

Answer 4

y?

Answer 5

because mit makes sense i guess

Answer 6

Answer 7

ohhhhhhhhhhhhhh

Answer 8

what does nucleus comprise of ??

Answer 9

Answer 10

ans my question

Answer 11

okay i dont know :(

Answer 12

is my diagram clear to you

Answer 13

u\yes

Answer 14

An atom consists of electrons and nucleus.
nucleus consists of proton and neutrons
protons consist of positive charge, electrons consist of negative charge and neutrons are neutral.
As such an atom is nuetral since \(\huge\color{gold}{\tt No~of~proton=No~of~electron}\)

Answer 15

are you understanding

Answer 16

yes

Answer 17

good

Answer 18

now mass of proton~ mass of electron

Answer 19

mass of neutron is negligible so we consider the mass of proton to calculate the atomic weight

Answer 20

oh okay

Answer 21

thanks

Answer 22

Electron
