Answer:Why is Dalton credited with proposing the first atomic theory if Democritus was talking about atoms almost 2,200 years earlier?
- Democritus' ideas were not supported by evidence
- Dalton's theory was the first scientific theory because it relied on scientific investigative processes.
- Dalton's theory was supported by evidence and repeated investigation.
Explanation: 1: Democritus' ideas were not supported by evidence
2: Dalton's theory was the first scientific theory because it relied on scientific investigative processes.
3: Dalton's theory was supported by evidence and repeated investigation.
Hence they got seven electrons in ground state
Relative atomic mass of NaCl=23+35.5=58.5
2000kg / 58.5 = mass per relative atomic mass = 34.188
34.188 * atomic mass of Na, 34.188 * 23 = 786.325... = 790 kg (2s.f.)
