Explanation:

The team number is the same as the number of the valence electrons each aspect within that team has. Therefore, two aspects in the same group will have actually the same variety of valence electrons. Because all bonding and/or ionizations show off the valence shell of electrons, atoms with the same variety of valence electrons behave similarly. Both tellurium and sulfur space in team VI, and 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 power level for each element. Therefore, two atoms found in the same row on the periodic table have actually the same power level. Potassium and selenium are both in row 4 of the routine table. Their highest energy level because that electrons is 4.


Explanation:

Ionization energy is the energy required to remove an electron. Noble gases are special due to the fact that the have a complete valence covering of electrons, which provides them the many stable elements, and also to eliminate an electron needs a many energy. The tendency for ionization energy is together follows: ionization energy increases indigenous left to right within a row and also from bottom to optimal within a team on the routine table. Every one of the answer options are in the exact same row the the periodic table, but fluorine is the furthest to the right. For this reason fluorine has actually the best ionization energy.

How many valence electrons does the element oxygen have?


Possible Answers:


*


*


*


*


Correct answer:


Explanation:

For neutral atoms, the variety of valence electron is equal to the atom"s main team number. According to the periodic table, oxygen is in team 6; therefore, it has actually 6 valence electron in its external shell.

Which the the adhering to is the most electronegative element?


Possible Answers:

Fluorine


Oxygen


Chlorine


None that the answer selections are correct


Nitrogen


Correct answer:

Fluorine


Explanation:

Generally speaking, as you go across a period and up a group on the routine table, electronegativity increases. Fluorine is the most electronegative element, v a Pauling range electronegativity ranking of about 4.0.

Example question #16 : The routine Table


Which of these elements is the very least likely to hold on come its valence electrons as soon as in the presence of a extremely electronegative atom?


Possible Answers:

Iron


Sodium


Cobalt


Cesium


Rubidium


Correct answer:

Cesium


Explanation:

Atomic radii boosts from right to left of the periodic table and that decreases bottom to top. For this reason francium, in the bottom left that the regular table, has actually the biggest atomic radius; helium, in the optimal right of the chart, has actually the smallest atomic radius. Based on these trends, cesium would certainly be least likely to organize on come its valence electrons since it has actually a larger atomic radius compared to cobalt or iron. To compare this come helium which has actually a tiny atomic radius and a complete valence shell of electrons, which renders it very stable.

Which that the complying with groups of elements would need the greatest influx of power to dislodge an 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 first ionization power to dislodge among their valence shell electrons because they have both the greatest electron affinity and also the smallest atomic radii. Since their electrons space both closer to their nuclei and halogens are more "electron greedy" (electronegative), castle require more energy to remove an electron. However, because the noble gasses have complete valence shells, they have the greatest first ionization energies.

You space tasked with packing a very tiny jar v as many individual atom of the same aspect as possible. Which facet would you pick 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 indigenous left to right across the regular table and increase from optimal to bottom of the periodic table. Based on these trends, helium has the smallest atomic radii and more atoms would fit inside our imaginary container.

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


Possible Answers:

Oxygen


Chlorine


Bromine


Fluorine


Nitrogen


Correct answer:

Fluorine


Explanation:

Electronegativity is the propensity of an atom to entice electrons come it. Electronegative atoms room electron "greedy". When they kind covalent bonds, very electronegative atom often form polar covalent bond in i m sorry the electrons spend a greater amount that time near the electronegative atom resulting in a dipole moment. Water is the quintessential example of a polar molecule. 

Electronegativity rises from left to right throughout the regular table and also increases native bottom to top as well. Fluorine is the many electronegative atom and also it would be most likely to result in a polar molecule. Save in mind that the development of a polar bond relies on the different electronegativities that the atoms in question. Because that example, two oxygen atoms execute not make a polar bond even though both atom are extremely electronegative.
