Answer : The number of valence electrons in fluorine are, seven.

Explanation :

As we know that the fluorine is a non-metal element that belongs to the group 17 and period 2. The symbol of fluorine element is, (F) and the atomic number of fluorine is, 9.

The electronic configuration of fluorine is, $1s^22s^22p^5$

Electronic configuration : It is defined as the distribution of electrons of an atom in an atomic orbitals.

From the electronic configuration, we conclude that the number of valence electrons present in fluorine is, seven (7).

Hence, the number of valence electrons in fluorine are, seven.

___AsCl3+____H2S-->___As2S3+___HCI

Alex17521 [72]

Answer:

2 AsCl₃ + 3 H₂S → As₂S₃ + 6 HCl

Explanation:

When we balance a chemical equation, what we are trying to do is to achieve the same number of atoms for each element on both sides of the arrow. On the right of the arrow is where we can find the products, while the reactants are found on the left of the arrow.

We usually balance O and H atoms last.

AsCl₃ + H₂S → As₂S₃ +HCl

reactants

As --- 1

Cl --- 3

H --- 2

S --- 1

products

As --- 2

Cl --- 1

H --- 1

S --- 3

2 AsCl₃ + H₂S → As₂S₃ +HCl

reactants

As --- 2

Cl --- 6

H --- 2

S --- 1

products

As --- 2

Cl --- 1

H --- 1

S --- 3

The number of As atoms is now balanced.

2 AsCl₃ + 3 H₂S → As₂S₃ +HCl

reactants

As --- 2

Cl --- 6

H --- 6

S --- 3

products

As --- 2

Cl --- 1

H --- 1

S --- 3

The number of S atoms is now equal on both sides.

2 AsCl₃ + 3 H₂S → As₂S₃ + 6 HCl

reactants

As --- 2

Cl --- 6

H --- 6

S --- 3

products

As --- 2

Cl --- 6

H --- 6

S --- 3

The equation is now balanced.

What do you call two or more atoms bonded together??

a_sh-v [17]

The definition for "What do you call two or more atoms bonded together" is a compound. Think of water. Water is called H20. Water is made of 2 hydrogen atoms and 1 oxygen atom. That is to atoms bonded together to make a compound which is water. Hope I helped
