Explanation:

The group number is the same as the number of the valence electron each facet within that group has. Therefore, two facets in the same team will have the same number of valence electrons. Since all bonding and/or ionizations show off the valence shell of electrons, atoms through the same number of valence electrons behave similarly. Both tellurium and sulfur are in group VI, and also have 6 valence electrons.

You are watching: Which of the following have the same number of valence electrons?


Explanation:

The period number/row number is the energy level because that each element. Therefore, two atoms found in the very same row ~ above the routine table have the same power level. Potassium and also selenium space both in row 4 of the routine table. Their highest energy level because that electrons is 4.


Explanation:

Ionization power is the energy required to eliminate an electron. Noble gases space special due to the fact that the have a complete valence covering of electrons, which renders them the most stable elements, and to remove an electron requires a most energy. The tendency for ionization energy is as follows: ionization energy increases indigenous left to best within a row and from bottom to top within a group on the periodic table. All of the answer choices are in the very same row the the periodic table, yet fluorine is the furthest come the right. For this reason fluorine has actually the biggest ionization energy.

How many valence electrons does the aspect oxygen have?


Possible Answers:


*


*


*


*


Correct answer:


Explanation:

For neutral atoms, the variety of valence electron is equal to the atom"s main team number. Follow to the routine table, oxygen is in group 6; therefore, it has actually 6 valence electrons in its outer shell.

Which that the complying with is the most electronegative element?


Possible Answers:

Fluorine


Oxygen


Chlorine


None of the answer options are correct


Nitrogen


Correct answer:

Fluorine


Explanation:

Generally speaking, as you go across a duration and increase a group on the regular table, electronegativity increases. Fluorine is the most electronegative element, with a Pauling scale electronegativity ranking of about 4.0.

Example question #16 : The routine Table


Which the these elements is least likely to host on to its valence electrons once in the visibility of a very electronegative atom?


Possible Answers:

Iron


Sodium


Cobalt


Cesium


Rubidium


Correct answer:

Cesium


Explanation:

Atomic radii rises from right to left of the routine table and the decreases bottom come top. For this reason francium, in the bottom left the the periodic table, has actually the biggest atomic radius; helium, in the optimal right the the chart, has actually the smallest atomic radius. Based on these trends, cesium would certainly be the very least likely to hold on come its valence electrons because it has a larger atomic radius compared to cobalt or iron. To compare this to helium which has actually a tiny atomic radius and a full valence covering of electrons, which provides it really stable.

Example question #17 : The regular Table


Which of the adhering to groups of aspects would need the biggest influx of power to dislodge one electron from its valence shell?


Possible Answers:

Transition metals


Alkaline earth metals


Alkali metals


Nonmetals


Halogens


Correct answer:

Halogens


Explanation:

Halogens would need the greatest an initial ionization power to dislodge among their valence covering electrons since they have both the best electron affinity and the smallest atomic radii. Since their electrons space both closer to their nuclei and halogens are an ext "electron greedy" (electronegative), they require much more energy to eliminate an electron. However, since the noble gasses have complete valence shells, they have the greatest an initial ionization energies.

You are tasked with packing a very tiny jar v as plenty of individual atom of the same aspect as possible. Which aspect would you choose to ensure the largest quantity that atoms would certainly fit in to the jar?


Possible Answers:

Francium


Boron


Radon


Helium


Hydrogen


Correct answer:

Helium


Explanation:

Atomic radii decrease from left come right across the routine table and increase from top to bottom of the regular table. Based on these trends, helium has the the smallest atomic radii and more atoms would fit inside our imagine container.

Which of these facets is most most likely to kind a polar bond?


Possible Answers:

Oxygen


Chlorine


Bromine


Fluorine


Nitrogen


Correct answer:

Fluorine


Explanation:

Electronegativity is the propensity of one atom to tempt electrons to it. Electronegative atoms are electron "greedy". When they kind covalent bonds, very electronegative atoms often type polar covalent bonds in i m sorry the electrons invest a better amount the time near the electronegative atom leading to a dipole moment. Water is the quintessential instance of a polar molecule. 

Electronegativity boosts from left come right across the regular table and also increases native bottom to top as well. Fluorine is the most electronegative atom and it would be most likely to result in a polar molecule. Keep in mind the the development of a polar bond counts on the different electronegativities the the atoms in question. For example, two oxygen atoms execute not make a polar bond also though both atoms are very electronegative.
