Answer:

The finding of the photon took place by the hypothesis that when a neutral atom of hydrogen loses an electron, a positively charged particle stays there within an atom. The proton refers to a subatomic particle, signified by the symbol p+, with a positive charge and +1e elementary charge and the mass somewhat less in comparison to that of a neutron.

It was discovered by Rutherford that the atom must exhibit a concentrated positive center charge, which comprises the majority of the mass of the atom. It was suggested by him that the nucleus comprises a constituent with a positive charge known as the proton.

When a neutral hydrogen atom loses an electron, a positively-charged particle should remain.

An alternative definition of electronegativity is Electronegativity= constant (I.E — E.A.) where I.E. is the ionization energy a

Kazeer [188]

Answer:

The electronengativity values of given elements is as follows.

Fluorine - 4

Chlorine -3

Bromine - 2.9

Iodine- 2.5

Explanation:

Electronegativity =consant (I.E-E.A)

The electron affinity and ionization energy values of the given elements is as follows.

(In attachment)

First we have to find the value of constant by using the fluorine atom to whom the electronengativity taken as "4".

Fluorine:

$4=constant[1678-(-327.8)]$

$Constant=0.0019942168$

By using this constant values we can find electronegatvity values of remaining elements.

Chlorine:

$Electronegativity=0.0019942168[1255+348.7]=3.1980\sim 3$

Therefore, electronegativity of chlorine is 3.

Bromine:

$Electronegativity=0.0019942168[1138+324.5]=2.91\sim 2.9$

Therefore, electronegativity of bromine is 2.9.

Iodine:

$Electronegativity=0.0019942168[1007+295.7]=2.59\sim 2.5$

Therefore, electronegativity of iodine is 2.5.

What is the best description of a molecule?

finlep [7]

Answer:

Three or more atoms bonded together

Explanation:

A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of atoms that are held together by chemical bonds

Three 10 g samples of sugar are represented in the diagram below. Sample A dissolves in water more slowly than sample B. Sample

lorasvet [3.4K]

Sample A dissolves most slowly because it tells us, first off, that A dissolves slower than B. It also tells that B dissolves more slowly than C. This means that’s A is slower than B and C, because there is no way A would be faster than C if B is already slower (because A is slower than B.) I hope this helps. :)
