The tendency of an element to loose an electron and gain positive charge is called metallic character. So an element which easily looses its electron/electrons are called metals. Hope it helps

If the grass contains 220,000 kcal of energy, who much energy will be available to the owl?
Anni [7]

Answer:

Generally, consumers only receive 10% of the energy from what they eat. So, if the grass had 220,000 kcal of energy, then the cow would receive 10% of that -  200kcal. And then when a human eats the cow, it will only receive 10% of the cow's energy. This is because within a food chain, energy is lost as organisms use their energy to survive - like moving and producing heat (if endothermic). So consumers do not get 100% of their food's energy. Hope this helps a little.

Classifying a carbon atom by the number of carbons to which it is bonded can also be done in more complex molecules that contain
defon

A sp³ hybridized carbon atom is the one which forms 4 single bonds with other atoms.

In the structure of Bilobalide, we can see 12 sp³ hybridized carbon atoms which are attached to other carbon, hydrogen and oxygen atoms.

In order to classify carbon atoms as 1°, 2°, 3°, or 4° we need to take a look at the atoms to which these carbon atoms are attached.

A 1° carbon atom is the one which is attached to only 1 carbon atom.

In the diagram, we can see 3 methyl groups ( -CH3) being attached to only 1 carbon atom. There is one more primary carbon atom.

There are 4 primary carbon atoms in Bilobalide.

A 2° carbon atom is the one which is attached to 2 other carbon atoms.

In Bilobalide we can see 4 secondary carbon atoms.

A 3° carbon atom is the one which is attached to 3 other carbon atoms.

In Bilobalide we can see only 1 tertiary carbon atom.

A 4° carbon atom is the one which is attached to 4 other carbon atoms.

In Bilobalide we can see 3 quaternary carbon atoms.

Please see the attached image for classification.
