Question

Using the periodic table entry below, match the phrases with their corresponding values. 1. atomic number 96 2. atomic mass 54 3. number of valence electrons 42 4. number of electrons in the n = 3 shell 18 5. number of neutrons 1

Answer 1

1. Curium

2. xenon

3.the element with valance electron 4 and 2 is Tin and lead

4. Nickel . if when n=3 , the number of electrons is 18 , then the total number of electrons will be 28 ; because there will be 2 electrons in n=1 and 8 electrons when n=2 using the equation$2n^{2}$ .Thus atomic number will be 28. The element with atomic number 28 is Nickel

5. Deuterium .Its an isotope of hydrogen. it has only one neutron

Answer 2

I have an answer!

1. The atomic number is 42.

2. The atomic mass is 96.

3. The number of valence electrons is 1.

4. The number of electrons in the n = 3 shell is 18.

5. Finally, the number of neutrons is 54.

Hopefully I helped you with this! God bless! :)
