Oxygen carries -2 charge
GrogVix [38]3 years ago
4 0

Answer:  -2

Explanation:

Following the shell distribution oxygen has a 2.6. configuration and an electronic configuration of [He]2{ s }^{ 2 }2{ p }^{ 4 }.This means that oxygen has 6 valence electrons that can be used in chemical reactions . In-order to obey the octet rule  it has to gain 2 more electrons to have a  2.8 shell configuration.An electron gain is usually denoted by a negative sign whereas a loss is denoted by a positive sign.Hence the -2   charge on the ion it forms.

How would results vary between observing a population directly as opposed to observing them indirectly?
ioda

Answer and Explanation:

Observing population directly gives you accurate result .

Direct observation does not need any intermediary as they themselves go for survey.

So, it is cost efficient.

Whereas indirect observing may involve manipulations.

It requires someone or many to hire who helps in surveying.

It incurs cost.

Thus, direct observation is always better than indirect observation.
