CO₂ does not have dipole-dipole forces as its strongest force.
Draw the 3D structures of each molecule. All have C-O, C-Br, or C-Cl <em>bond dipoles</em>.
In CO₂ the C-O bond dipoles point in opposite directions, so they cancel.
CO₂ has <em>no molecular dipole</em>. Its strongest intermolecular forces are <em>London dispersion forces</em>.
In all the other molecules, the C-Br, C-Cl, and C-O bond dipoles do not cancel. These molecules all have intermolecular dipole-dipole forces.
15 protons (atomic number is always the number of protons) 15 electrons because no charge was mentioned so it must be the same as protons 16 neutrons because mass number is the combined number of protons and neutrons
Speed = distance / time
s = 550 / 4
s = 137.5 m/s
In short, Your Answer would be Option B
Hope this helps!
Answer:
An atom becomes charged when there is an unequal amount of positive and negative particles in the nucleus.
An atom gets a positive charge when there is an increase in protons or a decrease in electrons, such that there are more protons than electrons in the nucleus.
An atom gets a negative charge when there is an increase in electrons or a decrease in protons, such that there are more electrons than protons in the nucleus.
An atom can get a charge with a change of particles in the nucleus if that change results in an uneven number of protons and electrons.
Explanation:
Because protons are positively charged particles and electrons are negatively charged particles, a neutral atom has an equal amount of protons and electrons, so that the opposite charges of the particles cancel each other out.
However, if there is an unequal amount of protons or electrons in the nucleus, the charge of the particles will no longer be canceled out, and the atom as a whole will take on a positive or negative charge.
