What are the elements located in Group 2 called?
Explanation
The elements located in Group 2 of the periodic table are called alkali earth metals. These elements include beryllium, magnesium, calcium, strontium, barium, and radium. They are called alkali earth metals because they are found in the earth's crust and have similar properties to the alkali metals found in Group 1. They are shiny, silvery-white metals that are relatively soft and reactive. The "the" before alkali earth metals in the answer is incorrect, as it is not necessary to use "the" when referring to this group of elements.Rate this question:

Check the boxes with the elements that are a part of the Halogens group (Group 17/Group 7).
-
Sulphur
-
Oxygen
-
Chlorine
-
Nitrogen
-
Boron
-
Iodine
-
Carbon
Correct Answer(s)
A. Chlorine
A. IodineExplanation
Chlorine and iodine are both elements that belong to the Halogens group (Group 17/Group 7). They exhibit similar chemical properties as other elements in this group, such as high reactivity and the ability to form salts with metals. Sulphur, oxygen, nitrogen, boron, and carbon do not belong to the Halogens group and have different chemical properties. Therefore, the correct answer is chlorine and iodine.Rate this question:

What's the one liquid on the Periodic table?
-
Mercury
-
Chlorine
-
Argon
-
Bromine
Correct Answer
A. BromineExplanation
Bromine is the correct answer because it is the only liquid element on the Periodic table at room temperature. Mercury is a liquid at room temperature, but it is not considered an element on the Periodic table. Chlorine and Argon are both gases at room temperature.Rate this question:

Here are 4 metals - Cesium (Cs), Gold (Au), Zirconium (Zr), and Mercury (Hg). Which is the most reactive and the least reactive metal?
-
Zirconium most reactive, Mercury least reactive
-
Gold most reactive, Cesium least reactive
-
Cesium most reactive, Mercury least reactive
-
Mercury most reactive, Gold least reactive
Correct Answer
A. Cesium most reactive, Mercury least reactiveExplanation
Cesium is the most reactive metal because it is located at the bottom left corner of the periodic table, which means it has the lowest ionization energy and is more likely to lose electrons and form positive ions. On the other hand, Mercury is the least reactive metal because it is a transition metal and is located towards the middle of the periodic table. Transition metals tend to have higher ionization energies and are less likely to form positive ions.Rate this question:

Here are 4 nonmetals - Sulphur (S), Chlorine (Cl), Selenium (Se), and Iodine (I). What is the most reactive and least reactive nonmetal?
-
Chlorine most reactive, Iodine least reactive
-
Selenium most reactive, Chlorine least reactive
-
Sulphur most reactive, Selenium least reactive
-
Iodine most reactive, Sulphur least reactive
Correct Answer
A. Chlorine most reactive, Iodine least reactiveExplanation
Chlorine is the most reactive nonmetal because it is highly electronegative and readily accepts an electron to achieve a stable electron configuration. On the other hand, iodine is the least reactive nonmetal because it has a larger atomic radius and is less likely to gain or lose electrons.Rate this question:

What's the electron configuration of the element in Group 1, Period 4? Write the answer, for example "1,1,1"
Correct Answer
2,8,8,1
2, 8, 8, 1Explanation
The given electron configuration, 2,8,8,1,2,8,8,1, represents the electron arrangement of two elements in Group 1, Period 4. The first element has an electron configuration of 2,8,8,1, which corresponds to potassium (K), while the second element has an electron configuration of 2,8,8,1, which corresponds to rubidium (Rb). Both potassium and rubidium have one valence electron in their outermost energy level, making them highly reactive alkali metals.Rate this question:

Answer the question in this order: 1. What's the most reactive nonmetal? Give me the full name of it. 2. How many electron shells does it have? 3. What is it's electron shell configuration? 4. What group and period is it in? Answer like this: answer to question 1, answer to question 2, answer to question 3, answer to question 4 Write electron shells like this "5 electron shells" Write electron configurations like this "1,1,1" Write groups and periods like this "group 1 and period 1"
Correct Answer
Fluorine, 2 electron shells, 2,7, group 7 and period 2
Fluorine, 2 electron shells, 2,7, group 17 and period 2Explanation
Fluorine is the most reactive nonmetal. It has 2 electron shells. The electron shell configuration of fluorine is 2,7. It is in group 7 and period 2.Rate this question:
