What was a major flaw in J. J. Thomson’s plum pudding model?

2 answers:

6 0

The plum pudding model<span> of the atom was not correct. The prediction that alpha particles would pass through a sample of matter and would be deflected only minimally was disproved by rutherford and co-workers who found that some alpha particles (1 in 8000) bounced almost straight back</span>

Explanation:

After the discovery of electron, J.J Thomson proposed 'Plum pudding model' in 1904. As per plum pudding model.

As per plum pudding model,

Positively charged is continuously spread through out the atom and the negatively charged electrons are embedded just like electrons embedded in plum.

Major Drawbacks of Plum pudding model:

As per Thomson's model, protons are uniformly distributed, but actually protons concentrated in a small region called nucleus.

According to Rutherford's model, electrons revolve around the nucleus in stationary orbitals. But in Thomson's model, electrons were embedded.

What does two bonded flurione atoms form?

Archy [21]

2 Fluorine atoms covalently bonded with each other, each sharing an equal number of a single, one valence electron to achieve a stable octet, would form a diatonic fluorine gas. It is a diatomic molecule, a molecule consisting of 2 atoms that are the same, in this case fluorine.

Answer:

A glass of mineral water is not pure water.

Explanation:

Pure chemical substances

Pouring water into a glass from a bottle

Food and drink may be advertised as ‘pure’. For example, you may see cartons of ‘pure orange juice’ or ‘pure mineral water’. This means that nothing else was added to the orange juice or mineral water during manufacture. However, these substances are not pure to a scientist. In science, a pure substance contains only one element or compound.

Mineral water is mostly water, but there are other substances mixed with it. These are the ingredients that you see listed on the bottle’s label.
