Question

question 4 (1 point)
which of these below has 74 protons and 73 electrons?
o a ta 1+
o b w 1-
o c w 1+
o d ta 1-

Explanation:

• The atomic number of an element is equal to the number of protons. Tungsten (W) has an atomic number of 74, so it has 74 protons.
• For a cation (positive ion), the number of electrons is less than the number of protons. The formula for the number of electrons in an ion is \( \text{Number of electrons}=\text{Number of protons}-\text{Charge}\).
• If the ion is \(W^{1 +}\), then the number of electrons \(=74 - 1=73\).

Answer:

C. \(W^{1+}\)
