It is a way to display to number of ________ for elements. This chart will show the correlation between ______ number and the nu
pav-90 [236]

Answer:

Electrons

Atomic number

Explanation:

The question describes a period table which is a chart of the elements.

The Periodic Table of elements shows the arrangement of elements based on their increasing atomic number.

In a neutral atom, the number of electrons will equal the number of protons, so we can easily determine electron number from atomic number. In addition, the position of an element in the periodic table—its column, or group, and row, or period—provides useful information about how those electrons are arranged (electronic configuration) in their different shells.

It is a way to display to number of ____electrons____ for elements. This chart will show the correlation between __atomic____ number and the number of valence electrons

Is this true or false the kinetic energy of a freely falling object decreases as it begins to fall
Naddika [18.5K]
The kinetic energy of an object is the energy of the object as it moves. It has more kinetic energy the faster it moves. Because a falling object is increasing in speed, it would also increase in kinetic energy. Hope this helps! :)

The Drude model uses Newton’s laws, which say that an electron in a constant electric field should experience constant accelerat
Troyanec [42]

Answer:

Electrons are influenced by internal forces.

-On the temperature, density of electrons per unit of volume and relaxation time.

-The temperature

Explanation:

The Drude model neglects interactions between electrons and ions and with themselves. Those interactions (by which we refer as electromagnetic forces) influence in the random movement and freedom of the electron. So, they could be more restricted or could influence in conductivity more.

The deduction of the resistivity comes from the Ohm's law, which states that the Electric field in the material is proportional to the current density of electrons by a constant, which is the resistivity itself. The equation goes as follows:

\rho=\frac{m_e}{e^2n_e \tau }

Where e refers to electron (or the charge of it), τ is the relaxation time (average time between collisions), m is the mass and n is the density of charges (electrons in this case) per volume. However, experimentally resistivity is also dependent on temperature, which actually influence the relaxation time. The thermal energy influence in the behavior of the electrons, making them collide with phonons, have more randomness and reduced mean free path.
