How many protons neutrons and electrons does cesium have?
The nucleus consists of 55 protons (red) and 78 neutrons (blue). 55 electrons (green) bind to the nucleus, with a single, relatively unstable electron in the outer shell (ring).
How many neutrons does titanium have?
Titanium-48 is a stable isotope containing 26 neutrons. 73.72% of natural titanium is titanium-48.
How many protons are in Ca?
If we could weigh individual atoms of calcium we would find some variation in their mass; this must be due to variations in the number of neutrons in their nucleus as all must have the same number of protons – 20. Atoms which have the same atomic number but different mass numbers are isotopes.
How do you find the electron configuration of calcium?
The number of electrons for the Ca atom is 20. Therefore the Calcium electron configuration will be 1s22s22p63s23p64s2. The first two electrons of calcium will go in the 1s orbital. The next 2 electrons for Calcium go in the 2s orbital.
How many protons neutrons and electrons does calcium 45 have?
The Ca 45 nuclide is an isotope of the element calcium (atomic number 20, chemical symbol Ca). The nucleus is made up of 45 nucleons, which consist of 20 protons and 25 neutrons.

How many valence electrons does calcium have?
From the electronic configuration we know that the outermost shell of Ca is the fourth shell and the number of electrons in that shell is the valence electrons. Here there are two valence electrons in the outermost shell. So the number of valence electrons in Ca is 2.
How do you find the electrons?
To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number: number of protons = atomic number. number of electrons = atomic number.
