Aparticle that has a negative charge:
a)electrons
b)neutrons
c)protons
d)non-polar molecule

Which is true of transition metals when moving from left to right on the periodic table? the d sublevels are not filled across the period. the cation radii become larger across the period. atomic radii increase slightly and then start to decrease. atomic radii decrease slightly and then start to increase. o

Chen drew a diagram to compare the ways in which different organisms obtain nitrogen. which label belongs to the area marked z?

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit
