On the basis of electronegativity, which of these pairs of elements is most likely to form monatomic ions?
mixer [17]

Answer is: Cl and Na.

sodium and chlorine are in third period and they have very different properties. Sodium is solid metal and chlorine is gaseous nonmetal.

They form compound NaCl (Sodium chloride), because sodium lost one valence electron and form cation Na⁺, chlorine gain one electron and form anion Cl⁻.

Electron configuration of sodium atom: ₁₁Na 1s² 2s² 2p⁶ 3s¹.

Electron configuration of chlorine atom: ₁₇Cl 1s² 2s² 2p⁶ 3s² 3p⁵.

Other examples are metal-metal pairs and they do not form cation and anion.

If a body with a mass of 4 kg is moved by a force of 20 N, what’s is the rate of acceleration ?
kaheart [24]

Answer:

The rate of acceleration is 5.

Explanation:

In order to calculate acceleration we need to divide the force by the mass.

Acceleration = net force/mass

In this case, it would be 20/4. Simplify that and we get 5.

If the dimensions of a cube-shaped cell with a volume of 1 pm were to
melamori03 [73]

Answer:

B

Explanation:

Assuming the units are all supposed to be the same

A cube shaped cell with a 1 um³ volume would have a dimensions of 1 x 1 x 1   (because volume = length x width x height and 1 x 1 x 1 =1)

If we double the dimensions, we have a cube with the dimensions 2 x 2 x 2.

The surface area of each face of the cube is the length x width, so 2 x 2. This means the surface area of each face of the cube is 4 um².

There are 6 faces of a cube, so the total surface area is 6 x 4 um² = 24 um².
