Calculate the mass defect and the nuclear binding energy of nitrogen-14. The mass of a proton is 1.00728 amu, and the mass of a neutron is 1.00866 amu.
The mass of a nitrogen-14 atom is 14.00307 amu.

The mass defect of nitrogen-14 is amu. Round to the 5th decimal place.

The nuclear binding energy of one nitrogen-14 atom is x 10A J. Round to 3 significant digits.

A:

it have destructive character

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
