In a hot star, a multiply ionized atom with a single remaining electron produces a series of spectral lines as described by the bohr model. the series corresponds to electronic transitions that terminate in the same final state. the longest and shortest wavelengths of the series are 63.3 nm and 22.8 nm, respectively. (a) what is the ion? (b) find the wavelengths of the next three spectral lines nearest to the line of longest wavelength.

Lightning is an example of what phenomenon? a release of a large amount of energyan absorption of a large amount of energya natural electric circuita natural electric current

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.

What electron configurations do atoms usually achieve by sharing electrons to form covalent bonds?
