The 4 indicates the number of electrons in the 2p orbital. In the electron configuration 1s2 2s2 2p4, it means there are 4 electrons in the 2p orbital of the atom.
4 is the mass number of helium (mass number = number of protons + number of neutrons)
Formation of CO2 and ethyl alcohol indicate anaerobic reactions.Formation of CO2 and ethyl alcohol indicate anaerobic reactions.
Groups represent vertical columns. They indicate different column with different properties.
They are unipotent.
The electron configuration of oxygen is 1s22s22p4.
O: 1s22s22p4

GohdImproved Answer:-Numbers were once formed on a tally stick whereas 4 notches would indicate 4 and 4 notches with a line through them would indicate 5 and so on.

The electron configuration 1s^22s^22p^4 corresponds to 6 valence electrons. This is because the electrons in the second energy level (2s^2 and 2p^4) are considered valence electrons as they are in the outermost energy level of the atom.
4, if the trailing zeros are there to indicate the precision. 2 otherwise.
3/4 agouti, 1/4 chinchilla
4, assuming the 0 at the end is to indicate the degree of precision.

BIRADS 4 means suspicious for cancer. A biopsy is usually recommended in this case.
When writing a range of numbers, square brackets are used to indicate the end number is included and round brackets are used to indicate the end number is excluded.examples:[1, 4] = all numbers ≥ 1 and ≤ 4(1, 4] = all numbers > 1 and ≤ 4[1, 4) = all numbers ≥ 1 and < 4(1, 4) = all numbers > 1 and < 4
