The element that has been a halogen from the given elements have been Chlorine. Thus, option A is correct.
Halogen has been given as the group of metallic compounds that have been consisted of the one valence electrons in their last orbitals.
The halogens have been the most reactive elements and belong to group 18 of the periodic table. From the given set of elements, the number of valence electrons in the following has been:
Since the element having 1 valence electron has been Chlorine. Thus, the element that has been a halogen from the given elements have been Chlorine. Thus, option A is correct.

Answer:
c. they are all used to diagnose medical conditions
Explanation:
Lactate dehydrogenase, aspartate aminotransfcrase, and creatine kinase all are used to diagnose medical conditions.
2.phenolphthalein
3.bromcresol green
Answer:
Ions of opposite charge strongly attract each other; those of like charges repel. As a result ions in an ionic compound are arranged in a particular manner.

Answer:
0,12 μmol/L of MgF₂
Explanation:
Preparation of solutions is a common work in chemist's life.
In this porblem says that you measure 0,00598 μmol of MgF₂ in 50,0 mL of water and you must calculate concentration in μmol/L
You have 0,00598 μmol but not Liters.
To obtain liters you sholud convert mL to L, knowing 1000mL are 1 L, thus:
50,0 mL (1L/1000mL) = 0,05 L of water.
Thus, concentration in μmol/L is:
0,00598 μmol / 0,05 L = 0,12 μmol/L -The problem request answer with two significant digits-

Answer:
There is no short answer.
Explanation:
In the given example Bobby is creating a solution for his bacteria count which consists of 1% bacterial sample.
Considering that the solution was mixed homogeneously, he can apply the procedure to the remaining sample and get the results he wants.
Or if the average number of bacteria in a 1 mL sample is known, he can apply that information proportionally to the 100 mL mixture and find the original cell concentration.
I hope this answer helps.
B He estimated the number of electrons in atoms of each element.
C He arranged the elements by different properties to find a pattern.
D He organized the elements by their atomic number.
Mendeleeve's periodic table was based on the atomic mass of each element.
The correct answer is option A: He determined the mass of atoms of each element.
The periodic table can be described as a regular arrangement of elements based on some periodic properties. The periodic table has evolved through the ages. Its patter has been changed several times before it arrived at its present form.
The Mendeleev periodic table was based on the mass of atoms of the elements. This table was published in Russia in 1869. His table even predicted elements that were yet to be discovered.
