Explanation:

The team number is the exact same as the number of the valence electrons each element within that team has. Therefore, two facets in the same team will have the same variety of valence electrons. Because 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 also sulfur space in group VI, and also have 6 valence electrons.

You are watching: Which element has 6 valence electrons

Explanation:

The period number/row number is the energy level because that each element. Therefore, 2 atoms discovered in the very same row on the periodic table have actually the same energy level. Potassium and selenium are both in row 4 that the periodic table. Your highest power level because that electrons is 4.

Explanation:

Ionization energy is the energy required to remove an electron. Noble gases space special due to the fact that the have a complete valence shell of electrons, which provides them the most stable elements, and also to remove an electron calls for a many energy. The tendency for ionization energy is together follows: ionization energy increases indigenous left to appropriate within a row and also from bottom to optimal within a group on the routine table. Every one of the answer options are in the exact same row of the routine table, yet fluorine is the furthest come the right. Therefore fluorine has the greatest ionization energy.

### Example question #14 : The routine Table

How plenty of valence electron does the aspect oxygen have?

Explanation:

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

### Example inquiry #15 : The regular Table

Which the the following is the most electronegative element?

Fluorine

Oxygen

Chlorine

None the the answer selections are correct

Nitrogen

Fluorine

Explanation:

Generally speaking, together you go throughout a period and increase a group on the routine table, electronegativity increases. Fluorine is the many electronegative element, through a Pauling range electronegativity ranking of about 4.0.

### Example inquiry #16 : The routine Table

Which of these aspects is least likely to organize on come its valence electrons as soon as in the presence of a highly electronegative atom?

Iron

Sodium

Cobalt

Cesium

Rubidium

Cesium

Explanation:

Atomic radii increases from right to left of the periodic table and it decreases bottom to top. For this reason francium, in the bottom left of the routine table, has the biggest atomic radius; helium, in the peak right that the chart, has actually the the smallest atomic radius. Based on these trends, cesium would certainly be least likely to host on to its valence electrons because it has a larger atomic radius compared come cobalt or iron. Compare this come helium which has actually a small atomic radius and a complete valence covering of electrons, which provides it an extremely stable.

### Example concern #17 : The periodic Table

Which the the following groups of elements would call for the best influx of power to dislodge an electron native its valence shell?

Transition metals

Alkaline earth metals

Alkali metals

Nonmetals

Halogens

Halogens

Explanation:

Halogens would require the greatest very first ionization power to dislodge among their valence shell electrons because they have both the best electron affinity and also the 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 eliminate an electron. However, since the noble gasses have full valence shells, they have the greatest very first ionization energies.

### Example concern #18 : The routine Table

You room tasked with packing a very tiny jar with as countless individual atom of the same element as possible. Which facet would you pick to ensure the biggest quantity that atoms would fit in come the jar?

Francium

Boron

Helium

Hydrogen

Helium

Explanation:

Atomic radii decrease native left to right across the regular table and increase from optimal to bottom the the periodic table. Based on these trends, helium has actually the the smallest atomic radii and more atoms would fit within our imaginary container.

### Example concern #19 : The periodic Table

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

Oxygen

Chlorine

Bromine

Fluorine

Nitrogen

Fluorine

Explanation:

Electronegativity is the tendency of an atom to tempt electrons come it. Electronegative atoms are electron "greedy". Once they form covalent bonds, highly electronegative atoms often type polar covalent bonds in which the electrons spend a greater amount of time near the electronegative atom bring about a dipole moment. Water is the quintessential example of a polar molecule.

Electronegativity rises from left to right across the regular table and increases native bottom to top as well. Fluorine is the most electronegative atom and also it would be most likely to an outcome in a polar molecule. Save in mind that the development of a polar bond depends on the different electronegativities that the atoms in question. Because that example, 2 oxygen atoms carry out not do a polar bond also though both atom are very electronegative.
