Question

write some point on atom ?

Answer 1

✡ ===================================✡


answer ⤵⤵⤵⤵

atom :-

it is the smallest particles of matter WHICH take part in a chemical reaction.


--> free existence of atom is not possible except :- Na atom , He atom.


fundamental particles of atom :-

electron ( e-)

absolute mass = 9.1 × 10^ -31

absolute charge = -1.6 × 10^-19

relative charge= -1


✡=========≠==========================✡

proton ( H+ or 1p^1)

absolute mass :- 1.673 × 10 -^27

absolute charge = 1.6 ×10-19.

relative charge = 1

✡ =====================================✡

neutron ( 0n^1)

absolute mass = 1.67 × 10^-27

relative charge = 0

Answer 2

Explanation:

An atom is a particle of matter that uniquely defines achemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons. Each electron is negatively charged. The nucleus is positively charged, and contains one or more relatively heavy particles known as protons and neutrons.
