How do you calculate the atomic number of an element?
protons + nuetrons
it is the protons
mass # - atomic #
How do you calculate the mass number of an element?
mass # - atomic #
protons + nuetrons
it is the number of protons
How do you find the number of neutrons in an element?
protons + neutrons
it is the # of protons
mass # - atomic #
Find the number of protons, neutrons, and electrons in Potassium 39, 40, 41.
Find the number of protons, neutrons, and electrons in Boron 10, 11.
Find the number of protons, neutrons, and electrons in Silicon 27, 28, and 29.
Which is bigger, Ga or Se, and why?
Ga; Ga has fewer protons to attract the electrons. Se has more protons which pull the electrons in and shrink the atom.
Se; Se has a larger atomic mass
Ga; Ga has a more protons than Se
Which has greater ionization energy, N or P, and why?
P has a greater ionization energy because its electrons are further apart
N has a greater ionization energy because its valence electrons are closer to the nucleus and harder to remove
N has a greater ionization energy because the valence electrons are further from the nucleus
Which has a greater electronegativity, Br or Cl, and why?
Cl has a greater electronegativity because the distance between chlorine’s nucleus and other electrons is less than the distance between bromine’s nucleus and other electrons.
Br has a greater electronegativity because the distance between chlorine's nucleus and other neutrons is less that the distance between Cl electrons.
Cl because the distance between the nucleus and the protons is not much
