Which of the following metal atoms would have the highest conductivity?A.the atom with the smallest radius and the fewest valence electrons
B.the atom with the smallest radius and the most valence electrons
C.the atom with the largest radius and the fewest valence electrons
D.the atom with the largest radius and the most valence electrons

Answers

Answer 1

Answer:

Answer: Option (d) is the correct answer.

Explanation:

A metal which has the largest size and the most valence electrons would have the highest conductivity because the larger is the size of a metal the more freely electrons can move in it. Hence, the metal can conduct electricity.

If the atom is smaller in size then the electrons will be tightly held around the nucleus and hence they won't be able to move freely. Therefore, they will not conduct electricity.

Thus, we can conclude that the atom with the largest radius and the most valence electrons would have the highest conductivity.

Answer 2

Answer:

D. the atom with the largest radius and the most valence electrons

Which of the following is NOT a common property of bases?a. feels slippery
b. tastes bitter
c. reacts with metals
d. changes colors of indicators

Answers

Bases are a class of compounds composed mainly of metal oxides and metal hydroxides. Bases exhibit the following properties:
Slippery feeling because they react with oils on the skin's surface to form soap.
Bitter taste
Changes color of indicators

However, bases do not react with metals. Therefore, the answer is C.

I believe that the best answer among the choices provided by the question isThey are made up of particles that are arranged in a repeating pattern.
Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.

Ionic compounds are made up of particles that are arranged in a repeating pattern. Therefore, the correct option is option C.

A specific class of chemical compound known as an ionic compound is created when two or more atoms share electrons. It is made up of anions, which are negatively charged ions, and cations, which are positively charged ions. Most frequently, ionic compounds are created when a metal interacts with a non-metal. The non-metal atom receives one or more electrons to become an anion during this reaction, whereas the metal atom loses one or more electrons to become a cation. The development of a stable ionic compound happens as a result of the electrostatic forces that draw these oppositely charged ions to one another.

What is the molarity of a solution where 1.00 gram of NaCl (MM 58.5 g/mol)is dissolved in enough water to make 415 mL of solution?
a. 4.12 x 10-5 M

b. 7.09 x 10-3 M

c. 4.12 x 10-2 M

d. 2.41 M

Answers

To find the molarity of the solution, we need to use the formula:

Molarity (M) = moles of solute / volume of solution (in liters)

First, let's calculate the number of moles of NaCl using its molar mass (MM):

Mass of NaCl = 1.00 gram

Molar mass of NaCl = 58.5 g/mol

Moles of NaCl = Mass of NaCl / Molar mass of NaCl

= 1.00 g / 58.5 g/mol

≈ 0.0171 mol

Next, we need to convert the volume of the solution from milliliters (mL) to liters (L):

Volume of solution = 415 mL = 415 / 1000 L

= 0.415 L

Now, we can calculate the molarity:

Molarity (M) = moles of solute / volume of solution

= 0.0171 mol / 0.415 L

≈ 0.0412 M

Therefore, the molarity of the solution is approximately 0.0412 M.

The closest answer option is c. 4.12 x 10^-2 M.

I hope this explanation helps! Let me know if you have any further questions.

How many electrons are in Br-? A) 4 B) 7 C) 34 D) 36 E) none of the above

Answers

The number of electrons in Br- (bromide ion) is option B) 7.

Bromine (Br) has an atomic number of 35, which means it normally has 35 electrons. However, since the bromide ion (Br-) has a negative charge, it has gained one extra electron, bringing the total number of electrons to 35 + 1 = 36.

So, the correct answer is not listed among the options given
