How many neutrons are emitted when a californium-249 nucleus (z=98) is bombarded with a nitrogen-15 nucleus to produce a 260105db nucleus? how many neutrons are emitted when a californium-249 nucleus (z=98) is bombarded with a nitrogen-15 nucleus to produce a db nucleus? a. zero b. two c. three d. four e. one

During the given fusion process, 4 neutrons are emitted.

Explanation:

In a nuclear reaction, the total mass and total atomic number remains the same.

The fusion reaction between californium-249 and nitrogen-15 nuclei, the equation follows:

To calculate Y:

Total mass on reactant side = total mass on product side

249 + 15 = 260 + Y(1)

Hence, during the given fusion process, 4 neutrons are emitted.

- 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
