<h3>Further explanation
</h3>
Given
Atomic symbol
Required
Atomic composition
Solution
Atomic number = number of protons = number of electrons
Mass Number (A) is the sum of protons and neutrons
Number of protons and Number of Neutrons in nucleus
Number of electrons in the shell
From the picture:
protons = 3
neutrons = 4
electrons = 3
atomic number = protons = electrons = 3
mass number = protons + neutrons = 3+4 = 7
Inert gases are also called noble gases. They are the elements found in Group 8A in the periodic table. They are inert because they don't react with other elements. This is because they have the most stable electronic configuration. That's why elements form ions to gain or give way electrons so that they conform with the electronic configuration of the nearest inert gas. Basing on the periodic table, the nearest inert gas to K is Argon. The nearest inert gas to I is Xenon.
Answer:
the answer is 4778.36
Explanation:
do pi time the radius squared times the height divided by 3
The ionization energy will increase substantially when 11th electron is removed compared to when the 10th electron is removed.
<h3>What is ionization energy?</h3>
Ionization energy is the energy required to remove one or more electrons from a neutral atom in its gaseous state to form a positively-charged ion.
The ionization energy increases steadily as successive electrons are removed from an atom. A substantial increase in ionization energy occurs with the removal of an electron from a filled inner shell.
The 10th electrons is the last electron in the L shell of atoms. The 11th electron is the first electron in a filled inner shell.
Therefore, ionization energy will increase substantially when 11th electron is removed compared to when the 10th electron is removed.
Note that there was no attached graph and the answer was given based on the general trend observed in ionization energies.

Formic acid, Sodium formiate will generate a buffer solution with pH around 3. 5.
It must consider the acid whose pKa = pH in order to choose the base or acid that can produce a buffer solution with such a pH of about 3.5.
However, it also need to consider buffer capacity, which is a factor that can alter the pH of a solution by one unit in a liter.
The connection between the components' concentrations and their concentrations themselves affects buffer capacity in addition to their individual concentrations.
Therefore, Formic acid, Sodium formiate will generate a buffer solution with pH around 3. 5.
