An atom of chlorine-35 contains 18 neutrons (17 protons + 18 neutrons = 35 particles in the nucleus) while an atom of chlorine-37 contains 20 neutrons (17 protons + 20 neutrons = 37 particles in the nucleus). Adding or removing a neutron from an atom's nucleus creates isotopes of a particular element.
Answer:oxygen is the central atom in water,it has two lone pairs of electrons, the bond angle is 104.27° The ideal H-O-H bond angle ought to have been 109.28°
Explanation:
The presence of lone pairs causes slight distortion in the bond angles of molecules. This distortion increases with the number of lone pairs present. Water has two lone pairs hence a greater distortion compared to ammonia.
C - electric charges have electric fields. imagine a magnet - charge is distributed in space in the same way magnetic field is. if you can imagine how two magnets of the same sign (++/--) repel each other, you can apply that concept to electric charge/field.
