Each atom is neutrally charged, which means that each atom has the same number
of protons and electrons. based on this, how many protons are in each atom?

Ineed ! it’s science and it’s due tomorrow!

Check the correct box to describe the periodic trends in electronegativity. electronegativity across a period: decreases. increases. electronegativity down a group: decreases. increases.

Express the following number in scientific notation. 0.026890 =
