Answer: The sodium ion has a smaller radius than the atom.

Explanation:

Atomic radii  is the distance from the center of the nucleus to the valence shell.

Na:11:1s^22s^22p^63s^1

Sodium atom being neutral has 11 protons and 11 electrons.

Na^+:10:1s^22s^22p^6

Sodium ion Na^+ has 10 electrons and 11 protons. Now 11 protons present in the nucleus can easily influence 10 electrons towards itself, the effective nuclear charge increases, the valence electrons are more tightly held by the nucleus and thus the size decreases.

PLZ HELP ME ASAP!!! 1 which of earths spheres contains most of its mass?
ivann1987 [24]

1. The answer is; C

The geosphere is made up of the physical rocks (composed of metals and minerals) and magma in the different layers. These densities of these rocks surpass those of other spheres such as the atmosphere and hydrosphere.


2. The answer is; B

Destructive forces break down land. Weathering and erosion are categorized as slow destructive forces because they take many years for their effect to be perceptible to the human's scale. Quick destructive forces are forces such as earthquakes and tsunamis.


3. The answer is; B

The atmosphere on earth is mainly composed of molecular nitrogen at 78%. Oxygen takes up 21% and other gases found in the atmosphere are hydrogen, carbon dioxide,ozone, dust, and water vapor at 1%.


4. The answers that apply are ; A & B

The formula for gravity force is given by the equation.; F(gravity) = (G*m1*m2)/d^2 where G is the gravitational constant, m1 and m2 are the masses of the two objects, and d is the distance between them.


5. The answer is; C

The force of inertia is due to their celestial mass. The larger the mass the higher the inertia. Inertia is the tendency of a moving object to maintain a straight path without an external force applied to it. This, therefore, prevents the moon from being pulled into collision with the earth. Gravity, on the other hand, prevents the moon from flying out of its orbit and away into space.

Sergeeva-Olga [200]
An object on the moon is 1/6 of the weight of an object on Earth

To find the answer to your question, divide the number of N on Earth by 6, 6N / 6 = 1N
