calculate the number protons, neutrons and electrons for K+, Cl-, and C

Expert Solution

K+ ------- Number of protons = 19 Number of protons is equal to atomic number of an element.

Number of netrons = 39-19 = 20 Number of neutrons = mass number - atomic number

Number of electrons = 18 Number of electons is equal to atomic number when the atom is neutral.

but for cation, subtract the charge and for anion , add the charge to the atomic number.

Cl- = number of protons = 17

= number of neutrons = 35.5-17 = 18.5

= number of electrons = 18

C = number of protons = 6

= number of neutrons = 12-6 =6

= number of electrons= 6.

A helium nucleus (called an alpha particle) contains 2 neutrons and 2 protons with no electrons. If any electrons are added, there is a negligible amount of mass added but obviously one negative charge per electron is added. Three particles are injected into a constant B-field of 2T at a velocity of 3×106ms. The first particle is only the alpha particle (He++), the second particle is a nucleus with 1 electron (He+), and the third particle is a nucleus with...
