Answer:
a. Sn or Si ⇒ Sn
b. Br or Ga ⇒ Ga
c. Sn or Bi ⇒ similar in size
d. Se or Sn ⇒ Sn
Explanation:
The larger atom has a larger atomic radius. We have to consider how varies the atomic radius for chemical elements in the Periodic Table. In a group (column), the atomic radius increases from top to bottom while in a period (file), it increases from right to left.
a. Sn or Si ⇒ Sn
They are in the <u>same group</u>. Sn is on the top, so it has a larger atomic radius.
b. Br or Ga ⇒ Ga
They are in the <u>same period</u>. Ga is located at the left so it has a larger atomic radius.
c. Sn or Bi ⇒ similar
They are not in the same group neither the same period. Bi is located more at the bottom, so it would be larger than Sn, but Bi is also at the right side, so it would be smaller than Bi. Thus, they have comparable sizes.
d. Se or Sn⇒ Sn
They are not in the same group neither the same period. Se is located at the top and right side compared to Sn, so Sn is the larger atom.
Answer:
Oppositely charged particles attract each other. This attractive force is often referred to as an electrostatic force. An ionic bond is the electrostatic force that holds ions together in an ionic compound.

Answer:
The type of bonding does carbon dioxide have is covalent bonding.
Explanation:
There are 2 broadly types of chemical bonds present:
1. <u>Covalent bond:</u> This bond is present when there is sharing of electrons between two elements.
2.<u> Ionic bond:</u> This type of bond is formed when there is a complete transfer of electrons from one element to another element. In this bonding one element is always a metal and another is a non-metal.
We are given that a carbon atom is double bonded to two oxygen atoms. <u>Carbon and oxygen both are non-metals and hence, the bonds between them will be purely covalent in nature.
</u>
Also, the valency of the carbon atom is 4. Thus, in the given case, the carbon atom is bonded to 2 oxygen atoms via double bonds. Thus, they all complete their octet by sharing the electrons.
<u>Hence, the type of bonding does carbon dioxide have is covalent bonding.</u>
Answer:
The answer is molarity.
Explanation:
I just took the test but you have to remember that the concentration of solutes in a solution is expressed as M which equals moles of solute/liters of solution. This is the definition of molarity.
I hope I helped! :D
