CArbon has an atomic number of 6. There are therefore only 2 electrons in C4+
Two.Titanium has an atomic number of 22.To check for unpaired electrons, you only need to check the valence shell, or the one that is not filled.1s2(2), 2s2(4), 2p6(10), 3s2(12), 3p6(18), 4p2(20),These shells are all filled, and there are two electrons left to go in the d shell. Because the d shell has five subshells, and electrons cannot pair until all subshells are filled, both these electrons are unpaired.
The nucleus contains protons and neutrons and is orbited by electrons. ( Apex 2021)
Protons, because electrons are equal to the atomic number and protons are equal to the number of electrons.
The atomic nucleus contain neutrons and protons.

Fluorine gas is diamagnetic as there are no unpaired electrons A neutral atom of flurine would be paramagnetic as due to the presence of 1 unpaired electron in a 2p atomic orbital

The electronic configuration for Cl atom is 1s2 2s2 2p6 3s2 3p5. It has one unpaired electron in the 3p shell, thus it is a free radical and very reactive. Hence chlorine does not exist in its atomic state as a Cl atom as it is too unstable.
