Explain the relation between valency and number of unpaired electrons

Answer»

First LET's start by treating the set of valence and unpaired electrons.

All unpaired electrons are valence electrons, but all valence electrons NEED not be unpaired. Got that? Good, now to the next of all things.

Unpaired electrons are electrons in an orbital which are are alone, while valence electrons are just electrons that are in the OUTERMOST SHELL of an atom.

For example, an atom has the electronic configuration
. Now here, the electron in the
orbital is both the valence and the unpaired electron, but what if we added another electron to the atom (just ASSUME we can do that). Then the configuration would change in the last orbital such that it will become
. Now the electron is only valence electrons, but not unpaired. This can be extended in many other ways, but this is the basic principle.

1)what is atomicity?​

Answer»

ANSWER:

Explanation:

Atomicity can be defined as the total number of atoms that COMPOSES a molecule. Simply PUT, it is the no of atoms present in a molecule. For example, each molecule of oxygen is composed of two oxygen atoms. So atomicity of oxygen is 2. In older CONTEXTS, atomicity is sometimes synonymous with valency.

why is there still a need for graphical evaluation of data in R² or the coefficient of determination of the best fit line?​

Answer»

Answer:

The coefficient of determination is a COMPLEX idea centered on the STATISTICAL analysis of models for data. The coefficient of determination is used to explain how much variability of one factor can be caused by its relationship to another factor.

Explanation:

R-squared is a goodness-of-fit measure for linear regression models. This statistic indicates the PERCENTAGE of the variance in the dependent variable that the independent VARIABLES explain collectively. ... After fitting a linear regression model, you need to DETERMINE how well the model fits the data.

So I had a thought, if you used a mixture of hydrogen and oxygen gas, then compressed it to the highest pressure, and then ignited the gasses with a spark. releasing a controlled explosion with force of 15,888 newtons out of 18 different exertion ports (8 on the upper back, 3 one each foot, and 1 on each hand). For a total of 286,000 newtons of upward thrust. could you theoretically make an working iron man thrusting system. Note: The above system would happen several times a second, kind of like the rpm of a car engine.
