Question

1. what is the isotope notation for a nucleus with 44 protons and 92 nucleons?
2. what is the atomic number for tellurium?
3. what is the name of the element with the symbol n?
4. what is the symbol for the element with atomic #60?
5. what subatomic particles are in an uncharged isotope with atomic number 95 and a mass number of 236?
6. what is the atomic number for mo?

Explanation:

1. Isotope notation

Step1: Determine atomic number (Z)

Atomic number \(Z\) is equal to the number of protons. Given 44 protons, so \(Z = 44\).

Step2: Determine mass number (A)

Mass number \(A\) is the number of nucleons. Given 92 nucleons, so \(A=92\).

Step3: Find the element symbol (X)

Looking up the element with atomic number \(Z = 44\) in the periodic table, the element is Ruthenium with symbol \(Ru\).

2. Atomic number of tellurium

Looking up tellurium (\(Te\)) in the periodic table, its atomic number \(Z = 52\).

3. Name of element with symbol \(N\)

Looking up the symbol \(N\) in the periodic table, the element is Nitrogen.

4. Symbol of element with atomic number \(Z = 60\)

Looking up the element with atomic number \(Z = 60\) in the periodic table, the element is Neodymium with symbol \(Nd\).

5. Subatomic particles in an uncharged isotope

Step1: Number of protons (\(\#p^{+}\))

Atomic number \(Z\) is equal to the number of protons. Given \(Z = 95\), so \(\#p^{+}=95\).

Step2: Number of neutrons (\(\#n^{0}\))

Mass number \(A = 236\), and \(A=Z + N\) (where \(N\) is the number of neutrons). So \(N=A - Z=236 - 95 = 141\), \(\#n^{0}=141\).

Step3: Number of electrons (\(\#e^{-}\))

In an uncharged atom, the number of electrons is equal to the number of protons. So \(\#e^{-}=95\).

6. Atomic number of \(Mo\)

Looking up Molybdenum (\(Mo\)) in the periodic table, its atomic number \(Z = 42\).

Answer:

1. \(A:92\), \(X:Ru\), \(Z:44\)
2. \(52\)
3. Nitrogen
4. \(Nd\)
5. \(\#p^{+}:95\), \(\#n^{0}:141\), \(\#e^{-}:95\)
6. \(42\)
