Introduction

In the realm of physics, electric fields play a crucial role in understanding the behavior of charged particles. When dealing with ions, it's essential to comprehend the direction and magnitude of their electric fields. In this article, we will delve into the specifics of electric fields and determine the values that should be used to complete a table for a magnesium ion.

Electric Fields and Ions

An electric field is a region around a charged particle where the force of the electric field can be detected. The direction of the electric field is defined as the direction of the force that a positive test charge would experience if placed in the field. For a magnesium ion, which has a positive charge, the electric field points away from the ion.

Properties of Magnesium Ion

Magnesium (Mg) is an alkaline earth metal with an atomic number of 12. When magnesium loses two electrons, it becomes a magnesium ion (Mg²⁺) with a charge of +2. The ion has a radius of approximately 72 pm and an atomic mass of 24.305 u.

Determining Electric Field Values

To complete the table, we need to determine the values of X, Y, and Z. These values represent the components of the electric field vector. Since the electric field points away from the ion, we can assume that the X, Y, and Z components are all positive.

Option A:

X : 14
Y : 12
Z : 12

In this option, the X, Y, and Z components are all equal, which is not a typical representation of an electric field. Electric fields are typically represented by a vector with three components, but these components are not necessarily equal.

Option B:

X : 12
Y : 12
Z : 12

In this option, the X, Y, and Z components are all equal, which is still not a typical representation of an electric field. However, this option is more plausible than Option A, as it suggests that the electric field is isotropic (equal in all directions).

Correct Option

To determine the correct values for X, Y, and Z, we need to consider the symmetry of the magnesium ion. Since the ion has a +2 charge, the electric field will be directed away from the ion. Assuming a spherical symmetry, the electric field will be radial and will have the same magnitude in all directions.

Calculating Electric Field Components

To calculate the electric field components, we need to use the following equations:

E_x = E * cos(θ) E_y = E * sin(θ) E_z = E * sin(θ)

where E is the magnitude of the electric field, and θ is the angle between the electric field and the x-axis.

Assuming a Spherical Symmetry

Since the magnesium ion has a spherical symmetry, we can assume that the electric field is radial and has the same magnitude in all directions. In this case, the angle θ is 0°, and the electric field components are:

E_x = E * cos(0°) = E E_y = E * sin(0°) = 0 E_z = E * sin(0°) = 0

Determining the Magnitude of the Electric Field

To determine the magnitude of the electric field, we need to use the following equation:

E = k * q / r^2

where k is Coulomb's constant (approximately 8.99 x 10^9 N m^2/C2), q is the charge of the ion (2 x 1.602 x 10^-19 C), and r is the distance from the ion (approximately 72 pm or 72 x 10^-12 m).

Calculating the Electric Field Components

Substituting the values into the equations, we get:

E = k * q / r^2 = (8.99 x 10^9 N m^2/C2) * (2 x 1.602 x 10^-19 C) / (72 x 10^-12 m)^2 = 1.38 x 10^11 N/C

E_x = E = 1.38 x 10^11 N/C E_y = E_z = 0

Conclusion

In conclusion, the correct values for X, Y, and Z are:

X : 1.38 x 10^11
Y : 0
Z : 0
