Answer:

Energy is absorbed, and an emission line is produced.

Explanation:

Electrons are present and revolving continuously in the orbits that are present around the nucleus. The energy of electron are fixed and unable to move to other orbits due to the strong attractive force of the proton which is present in the nucleus of the atom. If the electron wants to jump from the first energy level to the second energy level, so the electron has to absorb enough energy which can overcome the attractive force of proton.

In the molecule XeF2 the xenon uses which type of hybrid? O spºd O spºd? Osp? O sp3 Osp
ollegr [7]

Answer:

sp^3d

Explanation:

The hybridization of the any molecule can be calculated by the formula \frac{number\ of\ valence\ electron\ of\ central\ atom+number\ of\ monovalent\ atom\ -chare\ with\ sign}{2}

We know that Xe have 8 valence electron and 2 monovalent atom  (F) are attached with Xe and there is no charge

So hybridization =\frac{8+2-0}{2}=5

So the hybridization will be sp^3d

Note -

2 for sp

3 for sp^2

4 for sp^3

5 for  sp^3d

Which best describes how Dalton's early theory of atomic structure differs with modern theories? He did not know -
Alja [10]
<span>John Dalton introduced a theory proposing that elements vary because of the mass of their atoms.
He said in his theory that all matter is made up of indivisible blocks called atoms. He also stipulated in his theory that elements are identical thus, have different sizes and masses.
Dalton's theory was different from Niels Bohr who proposed a new atomic model which was also commonly known as the modern atomic theory. Bohr's theory says that atoms are arranged in circular orbits around the nucleus. He patterned his model as the solar system.
