An atom with one valence electron combines with an atom with seven valence electrons.

1 answer:

6 0

The atom with one valence electron is likely to lose its electron to form an ion with a +1 charge.

The principle behind this is simple. Atoms wish to have a stable electronic configuration, which requires that their valence shell be complete. If an atom has only one valence electron, then in order to achieve stable configuration, it is easier for it to get rid of the electron and move back to its last completed shell instead of trying to gain 7 electrons to complete the current valence shell.

Sun spots- dark circles on the sun’s surface that I believe are areas of cooler temperatures.
Solar flares- arcs of fire that leap from the sun’s surface. Nothing special, they’re a daily roumaine for the sun

What must happen to the atoms before they are accelerated in the mass spectrometer?

ira [324]

Answer:

Atoms and molecules can be deflected by magnetic fields - provided the atom or molecule is first turned into an ion. Electrically charged particles are affected by a magnetic field although electrically neutral ones aren't. The atom or molecule is ionised by knocking one or more electrons off to give a positive ion.
