Answer : Fluorine has Seven valence electrons.

Explanation :

Element = Fluorine

Atomic number = 9

Number of electrons = 9

Electronic configuration = 1s^22s^22p^5

Electron structure is also known as electronic configuration. It is defined as the arrangement of electrons of an atom in an atomic orbitals.

According to Electron configuration, the 2s and 2p are the outermost energy shell and the number of electrons in 2s and 2p are 2 & 5 respectively. That means Fluorine has '7' valence electrons.

The electron structure of fluorine is shown below.

ehidna [41]

Answer:

<u>reaction are equal.</u>

Explanation:

The law of the conservation of mass states that the total mass before and after a reaction are equal.

In a reaction, the mass of the reactants are always equal to the mass of the products. Nothing ever disappears from the equation, although substances may become gas and "disappear" the air.

given that the speed of light is 2.998 x 108 m/s, what is the frequency of a wave that has a wavelength of 3.55 x 10-8 meters
Vesna [10]
Frequency, f = v / λ

f = 2.998 * 10⁸ / 3.55*10⁻⁸

f = 8.445 * 10¹⁵ Hz.

Why is NH3 soluble in H20 but NCl3 is not?
storchak [24]
NH3 is soluble in water because it has the same amount of intermolecular forces as water. NH3 is a polar molecule and water  is a polar molecule so they dissolve each other. NCl3 does not dissolve in water because it is a nonpolar molecule which is different with water. NCl3 is nonpolar due to the difference in electronegativities between 3 atoms of Cl and 1 atom if N2.
