Answer:
Tin (Sn) as in the periodic table the element tin has 50 protons
Inertia. The first law of motion is often called the law of inertia. ... Inertia causes a moving object to stay in motion at the same velocity (speed and direction) unless a force acts on it to change its speed or direction. It also causes an object at rest to stay at rest.
Yes because the group number is the number of electrons in their outermost shell.
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.
