Explanation:

Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from Earth — and absolute magnitude — how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs.

The measurement of a star depends on the distance of the star from earth

is Apparent magnitude.

The apparent magnitude of a star is how bright the star appears in the sky

from the earth. The apparent magnitude of a star depends on two main

The relationship between an hydrogen atom's energy levels, sublevels and atomic orbitals lies in the fact that hydrogen atom has a shell with energy level of 1 and the energy sublevels are similar as there's only one and have the same energy, and lastly, only one atomic orbital exists in a hydrogen atom

Ultimately, the hydrogen atom has only one electron In the energy level 1, sublevels with equal energy as there are no sublevels in the energy level 1 and only the 1s atomic orbital.

The age of the artifact is equal to 2.5 × 10³ years when the half-life of carbon- 14 is 5.73 × 10³ years.

The half-life of a radioactive element is defined as the time that is required to decrease the original quantity of a radioactive isotope to half after decay.

The half-life of a radioactive isotope is the feature of the element and does not depend upon the actual amount of the radioactive isotope.

Given, the ratio of the initial and left amount of  ¹⁴C is :

N = 0.745 N₀

The half-life period of the ¹⁴C isotope = 5.73 × 10³ years

The rate constant of the decay of radioisotope can be calculated from the below-mentioned formula:

[tex]\displaystyle k=\frac{0.693}{t_{1/2}}[/tex]

[tex]\displaystyle k=\frac{0.693}{5.73 \times 10^3}[/tex]

k = 0.123 × 10⁻³ yr⁻¹

The age of the artifact can be calculated as:
[tex]\displaystyle t =\frac{2.303}{k} log\frac{N_0}{N}[/tex]

[tex]\displaystyle t =\frac{2.303}{0.123\times 10^{-3}} log\frac{N_0}{0.735 N_0}[/tex]

t = 2.5 × 10³ years

Answer:

One Lone Pair. (I think)

Explanation:

Answer:

there is no following so sorry

Based on the trend of electronegativities values of the elements Be, Mg, Ca, and, Sr within their group (increasing from bottom to top), the atoms of the element Sr will have the least attraction for an electron.  

We need to remember that electronegativity indicates the affinity or attraction of an element for an electron. Hence, the higher the electronegativity, the higher the attraction of that element for an electron.  

The values of electronegativities of the given elements are the following:

Be = 1.57

Mg = 1.31

Ca = 1.0

Sr = 0.95

We can see that the increasing trend of electronegativities in this group is from the bottom to the top, having the Sr with the lowest electronegativity value and the Be with the highest.  

This trend is related to atomic size, the larger the atomic size, the lower the electronegativity because the electron in the outermost shell will feel less attraction towards the nucleus of an atom. In a group of the periodic table, the size of an atom will increase from top to bottom.          

Therefore, according to the said above, the atoms of the Sr will have the least attraction for an electron (it has the lower electronegativity value).
