Acidic oxides, such as sulfur dioxide and nitrogen oxides, mix with water in the atmosphere and form acids such as sulfurous acid.

Ronak Singh

Acidic oxides are the oxides of non-metals. Basic oxides are the oxides of metals.

Bronsted acids donate protons, and Bronsted bases accept protons.

Ronak Singh

Technically it is possible in certain conditions, but there are usually more acidic species in the atmosphere that over power the basic species and result in rain usually being slightly acidic.

Ronak Singh

According to the Bronsted Lowry definition, acids donate protons and bases accept protons.

Ronak Singh

According to the Lewis definition of a base, a base is a lone pair donor.

I think we will be going over acid rain next week in class.

The position of atoms around the central atom doesn't matter because all of the bond angles are the same.

Ronak Singh

S character is the proportion of the number of hybrid orbitals that the s block contributed. For example in sp3 hybridization, there are 4 orbitals and only 1 is from the s block so there is 25% s character.

Ronak Singh

The 3 in sp3 means that out of the 4 total hybrid orbitals, 3 come from p orbitals.

Ronak Singh

A molecule is linear if there are 3 unshared pairs around the central atom because the 3 lone pairs occupy a horizontal plane and the two bonding atoms occupy a vertical plane.

The shape of ch2cl2 is tetrahedral so the chlorine atoms are 109.5 degrees away from each other, not opposite from each other. This causes dipole moments towards the chlorine atoms which do not cancel.

Ronak Singh

It is usually determined through experimental data.

Ronak Singh

Because it always takes energy to break bonds, bond dissociation energy is always positive.

Ronak Singh

Polarizability is the ease of the distortion of the electron cloud of the atom or molecule.
Polarizing ability is how easily an atom or molecule can distort the electron cloud of another atom or molecule.

Ronak Singh

Lattice energy is the energy required to break apart an ionic solid and convert its component atoms into gaseous ions.

Ronak Singh

Effective nuclear charge is the net positive charge experienced by an electron in an atom.

Ronak Singh

The atom with the lowest electronegativity should be placed in the center.

Ronak Singh

The central atoms usually have the expanded octet because they form the most bonds.

Bozeman science videos are helpful.

It can be measured in angstroms. 1 angstrom is equivalent to 1*10^-10 meters.

Valence electrons are outer shell electrons that are the furthest away from the nucleus.

The spin of an electron is the 4th quantum number.

Ronak Singh

Electrons further away from the nucleus are bound less tightly to the nucleus because the effective nuclear charge is reduced because of the distance between the nucleus and the electron, and because electrons that are closer to the nucleus "shield" or block some of the positive charge of ...

The photoelectric effect is the emission of electrons from a material due to the shining of a light.

Ronak Singh

Electrons can move to higher energy levels when they are "excited" by absorbing extra energy. When electrons move down from their excited state to a ground state, they release this extra energy in the form of a photon.

Ronak Singh

De Broglie's equation is the relationship between wavelength and objects that have a mass and velocity. It suggests that all objects with momentum can exhibit wavelike properties, although some objects have wavelengths that are currently undetectable.

Ronak Singh

Yes, the energy in both equations should be equivalent.

No, I do not believe it does.

I asked the guy next to me if he had any sodium hypobromite.
He said NaBrO.

Don't trust atoms...they make up everything!
