Question

Which of the following is true? The probability density ______________ is independent of direction from the nucleus foe 1s orbitals only. for all s orbitals is independent of direction from the nucleus. for all s orbitals is independent of distance from the nucleus. is independent of distance from the nucleus for 1s orbitals only. A baseball with a mass of 150 g is moving at a velocity of 40 m/s (90 mph). If the uncertainty in the velocity is 0.1 m/s, the uncertainty in position ________________ must be less than or equal to 4 times 10^-33 m. may be zero. must be greater than or equal to 4 times 10^-33 m. must be 4 times 10^-33 m. Which of the following is true? ______________ the square of the wave function gives the probability of finding the electron. There is a 5% chance of finding an electron in an atom outside is orbital. The bohr atom is the model currently accepted for electrons in atoms. Electrons travel around the nucleus in circular orbits. Which element has the most favorable (most negative) electron affinity? I Be K Ne How many electrons are in the outermost shell of the Sn^4+ ion in its ground state? 18 2 4 8 Which of the above pictures best represents a solid ionic compound? picture (a) picture (b) picture (c)

Explanation / Answer

Ans 14) all the s orbitals are spherical symmetrical and we can't able to define any specific direction in spherical symmeterical object from its center ( in this case spherical symmeterical object is s orbital and center is nucleus.) which means all the direction from nucleus is equivalent.

Therefore probability density is independent of the direction for all s orbitals

But yes it depends on the distance from the nucleus.

Therfore option b is correct
