What is the second row anomaly?

ELEMENTS. Li, Be, B, C, N, O, F. For the elements in the 2nd row, as the atomic number increases, the atomic radius of the elements decreases, the electronegativity increases, and the ionization energy increases.

Why bromine oxides are unstable?

This is because all ten electrons in the bromine atom’s third orbital (3d) are comparatively close to the nucleus and exert comparatively less repulsion on the five electrons in its fourth orbital (4p).

What is the order of stability of oxides of halogens?

Thus, the stability of oxides of halogens decreases in the order : I > Cl > Br > F.

Why are higher oxides of halogens more stable?

Because the higher ones are less reactive than the lower ones and also the size of the atoms are more of higher so they are less reactive and hence the oxides are more stable .

What is the second row on the periodic table?

The second period contains the elements lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon. In a quantum mechanical description of atomic structure, this period corresponds to the filling of the second (n = 2) shell, more specifically its 2s and 2p subshells.

What is meant by inert pair effect?

The inert-pair effect is the tendency of the two electrons in the outermost atomic s-orbital to remain unshared in compounds of post-transition metals. As a result, the inert pair of ns electrons remains more tightly held by the nucleus and hence participates less in bond formation.

What is meant by higher oxides?

higher oxides means element who make bond with oxygen is more strong and stable. e. for example. 2Zn + O2 -> 2ZnO. here zinc oxide is more stable .

What are oxides of halogen?

Fluorine reacts readily with oxygen and forms difluorine oxide and difluorine dioxide where it has a -1 oxidation state. Fluorine reacts readily with oxygen and forms difluorine oxide (F2O) and difluorine dioxide (F2O2) where it has a -1 oxidation state.

Why is iodine more stable than chlorine?

Because the undesirable overall negative charge in iodide is spread out over a larger volume/atomic radius than in chloride, iodide is more stable than chloride.

What do you mean by higher oxides of halogen?

higher oxide halogens are more stable than the lower ones because the higher ones are less reactive than the lower ones and also the size of the atoms are more of higher so they are less reactive and hence the oxides are MORE stable.

Why does the 2nd row of the periodic table have 8 elements?

Second shell has two sub shells 2s and 2p which have a total of four orbitals hence eight electrons can be successively filled in the four orbitals and hence 2nd period has eight elements.

Which is the best definition of an anomaly?

› a person or thing that is different from what is usual, or not in agreement with something else and therefore not satisfactory: Statistical anomalies can make it difficult to compare economic data from one year to the next. The anomaly of the social security system is that you sometimes have more money without a job.

What is the definition of an eccentric anomaly?

Also called: eccentric anomaly the angle between the periapsis of a particular point on a circle round the orbit as seen from the centre of the orbit. This point is obtained by producing a perpendicular to the major axis of the ellipse through the orbiting body until it reaches the circumference of the circle.

What does an anomaly on a tax return mean?

The government does computer checks of tax returns to find anomalies that might indicate fraud. These surfaces are distorted by hydrostatic balance toward negative anomalies of pressure produced by the bend of the low-pressure vortex cores.

What do you mean by anomaly in Maine?

But the Maine law, which permits the importation of liquor into the state, whilst it prohibits its sale, is a useless anomaly. A giant with the tastes and disposition of a schoolgirl was an anomaly in a Swiss village. What Do “a.m.”
