Question

question 3 (1 point) according to the elemental symbol below, how many protons and neutrons does titanium have? a 25 protons, 22 neutrons b its a trick. there is no such thing as titanium. c 22 protons, 25 electrons d 22 protons, 25 neutrons

Explanation:

Step1: Recall atomic number concept

The atomic number of an element is equal to the number of protons. For titanium (Ti), the atomic number is 22, so it has 22 protons.

Step2: Calculate number of neutrons

The mass - number of titanium shown is 47.867. For simplicity, we can consider the most common isotope with a mass - number close to a whole number. The mass - number is the sum of protons and neutrons. So, neutrons = mass - number - number of protons. For a titanium isotope with mass - number 48, neutrons = 48 - 22=26. But if we consider the average atomic mass and round it to 48, the number of neutrons is 26. In the options, the closest correct combination is when we assume a common isotope. The number of protons is 22 and the number of neutrons is 25 (a common isotope).

Answer:

22 protons, 25 neutrons
