Why does selenium not have a second electron affinity?

It does.

How do you create an electron affinity reactor?

To create an electron affinity reactor you will have to use the second ionization energy.

Would you expect the second electron gain enthalpy of O as positive more negative or less negative than the first Justify your answer?

The second electron gain of an oxygen atom would be expected to be less negative. The reason for this outcome is that the oxygen atom gaining a second electron already has one electron and thus a negative charge. This negative charge repels the second electron to some extent, making the enthalpy of this process less negative than when the first electron was added to the neutral oxygen atom.

Why oxygen is having two electron affinity?

First EA is usually exothermic as energy is released when the nucleus attarcts an electron is larger than the energy taken in to overcome their inter-electronic repulsion. Second EA is always endothermic since electron is added to a negative ion. Energy is needed to overcome the repulsion between the two negatively charged species.

What is negative seven in Parentheses to the second power?

positive 49 Because a negative times a negative is a positive. -7*-7=49. positive * positive = positive negative * negative= positive positive * negative = Negative

What elements has the largest electron affinity?

AnswerElectron affinity is the energy released when we add an electron to the outermost orbit of the atom. Halogens are the higher in electron affinity, and chlorine has the higher electron affinity than rest of the halogens. The irregularity in the electron affinity trend between Cl and F is due to the small size of the F atom. Although F definitely has a higher attraction for an electron than Cl (as evidenced by its high electro negativity value), the small size of the F atom means that adding an electron creates significant repulsion. Since electron affinity is an energy measurement, the total energy associated with electron affinity winds up being the energy that is released by the electron binding to the nucleus, minus the energy involved in overcoming the electrical repulsion in the outer shell.This makes the fluoride anion so formed unstable due to a very high charge/mass ratio. Also, fluorine has no d electrons which limits its atomic size. As a result, fluorine has an electron affinity less than that of chlorine.

What terminal does electrons flow from in a dry cell?

That is a good way to run the cell down quickly. Electrons are negatively charged so they always move from the positive terminal towards the negative. Each electron carries a charge of 1.602 x 10-19 coulombs so 1 coulomb (1 amp for 1 second) carries 6.24 x 1018 electrons.

What are the coordinates of a point that could be in each of the four quadrants?

The coordinates must be as follows: First quadrant: positive, positive Second quadrant: negative, positive Third quadrant: negative, negative Fourth quadrant: positive, negative

A negative plus a negative is positive?

No a negative plus a negative is not a positive answer. example. -5+-2=-7 but if you are subtracting a negative number from a negative, then the second negative number would become a positive. example. -5 - -2= -5+2= =-3

Are there any trends to the periodic table?

Atomic Radii,Ionic Radii, First Ionization Energy,Second and Higher Ionization Energies, Electron Affinity.

Given the trinomial where both the first sign is positive and the second sign is negative the signs of the factors will be?

One positive one negative (apex)

Is a negative number minus another negative a positive number or a negative number?

the answer is negative number It depends on the second number because in 6minus-7. the seven would turn positive and therefore the answer is positive. Because you would add the opposite.
