Calculate the wavelengths of the first 4 lines in the Ballmer emission spectrum of hydrogen (n1 – 2 and n2 – 3,4,5). Work in ev units for energy. Refer your answers to the colour as demonstrated in the
line spectra.

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
