Answer:
Protons: 22
Neutrons: 26
Electrons: 22
Explanation:
Titanium's atomic number is 22, meaning that the number of protons it has in its nucleus is also 22. # of electrons = # of protons, so the number of electrons is also 22. Titanium has an atomic mass of 47.867, but we can round up to 48. To find the atomic mass, we add up number of protons and neutrons. We know the number of protons as 22, so we subtract 22 from 48 and get a number of 26. Thus, the number of neutrons is 26.

Answer:
1.51 x 10²⁴atoms
Explanation:
Given parameters:
Number of moles of Cr = 2.50mol
Solution;
what is a mole;
a mole of any substance is the amount of substance that contains the avogadro's number of particles which is 6.02 x 10²³ particles
The particles here can be atoms, protons, neutrons, electrons e.t.c
1 mole contains 6.02 x 10²³ atoms
2.5 moles will contain 2.5 x 6.02 x 10²³ = 1.51 x 10²⁴atoms
...........................................Yes this is true
