Students are completing a table about a particular subatomic particle that helps make up an atom.

defon

Answer: option B.with “Inside the nucleus,” because the particle is a neutron.

Explanation:

You have to <u><em>complete this table</em></u>:

mass | location | charge

1 ? Has no charge

<em>The atom</em> is constituted by <em>3 subatomic particles</em>, namely electron, proton, and neutron.

Since the gold foil experiment performed by Geiger and Marsden (1909), who collaborated with Ernest Rutherford, it was stablished that the atom contains a dense positively charged nucleus, which has almost all the mass of the atom.

The positive charge comes from the subatomic particle named proton.

A few time later, a second subatomic particle inside the nucleus, was discovered. This particle has not charge and has almost the same mass than the proton. Because the absence of charge it was named <em>neutron</em>.

Hence, the relative masses of the protons and neutrons are 1 / 1. As said, both are in the <em>nucleus</em>, and while the proton has positive charge, the <em>neutron has no charge</em>. So, <em>the table is completed with inside the nucleus, because the particle is a neutron</em><em>:</em>

mass | location | charge

1 inside the nucleus Has no charge

The Quantum Mechanical Model is used to describe:

gayaneshka [121]

The quantum mechanical model is used to describe the energy and most likely location of an electron.

Answer: Option A

<u>Explanation: </u>

The quantum mechanical model leads to the introduction of quantum numbers representing the energy levels, sub-shells, orbitals as well as spin states of the electrons. So according to the quantum numbers we can perfectly define the position and energy of any electron in an element.

According to Pauli’s principle, any two electron cannot be having same set of quantum numbers. So, using the principle quantum number, azimuthal quantum number, magnetic and spin quantum number, we can define the energy and location of an electron in the atom.

Which defines the average kinetic energy of a system's particles?

ch4aika [34]

<h2>Answer:Temperature</h2>

Explanation:

Average kinetic energy of a system of particles is given by $\frac{f}{2} kT$ .

where,

$f$ is the number of degrees of freedom of the particles.

$k$ is the boltzmann constant.

$T$ is the temperature.

For general gases,

$f=3$

For a given degrees of freedom,average kinetic energy is directly proportional to temperature.

So,the average kinetic energy depends on temperature.

Structure of 2,3-dimethylheptane

olga55 [171]

Answer:

Please find the structure of the hydrocarbon in the attachment section and details on how to draw it in the explanation section.

Explanation:

Heptane is a member of the alkane group, which has a general formula of CnH2n+2. If n in heptane is 7, this means that the chemical formula for heptane will be C7H16 i.e.

= C7H2(7) + 2

= C7H14+2

= C7H16

C7H16 is the chemical formula for heptane, which is a linear hydrocarbon with 7 carbon atoms and 16 hydrogen atoms. However, in the name of the hydrocarbon compound given in the question: 2,3-dimethylheptane;

- Two methyl groups (CH3) has a substituted two hydrogen atoms specifically at carbon 2 and 3 respectively. Therefore, the new chemical formula of 2,3-dimethylheptane will be: C7H14(CH3)2

Please find the structural formula of the compound; 2,3-dimethylheptane as an attachment.
