The element is determined by the atomic number - the number of protons in the nucleus. In this case, element 36 is Krypton. The mass is the sum of protons and neutrons in the nucleus. Here we have a mass of 77, and a quick check confirms that an isotope of Krypton with a mass of 77 does indeed exist.
If it has 36 protons and 36 electrons, the charge would be zero. If it has 36 protons, it has to be krypton since the number of protons identifies the element. Having only 41 neutrons seems unusual as it should have 48 neutrons.
This is the isotope krypton-77.
Unknown, because it is 'plasma'-like, not normal pure element of one kind.
I can answer this if it were Carbon(atom number 6 in the periodic table), 'c-4' is unknown to me as element. C-4 ion does not exist and should preferably be written as C4-. Berillium is atom no. 4.So:C has 6 protons and 6 electronsNeutron number is different for each type of isotope:Isotope C-12, with mass number 12, has 6 neutronsIsotope C-13, with mass number 13, has 7 neutronsIsotope C-14, with mass number 14, has 8 neutrons
Neutrons and protons are bound together in the nucleus at the center of the atom; electrons occupy various orbitals or energy levels outside and around the nucleus. Neutrons are neutral or have no charge, protons have a positive charge; electrons a negative charge.
Boron-11 has 5 protons and 6 neutrons. This is because each element has a specific number of protons in its atoms that never changes. Boron atoms always have 5 protons. And when the number of protons (5) is subtracted from the mass number (11), the result is the number of neutrons (6).
18. Phosphorus has an atomic number of 15, therefore it has 15 protons. Phosphorus-33 has a total of 33 protons and neutron and therefore has 18 neutrons. Phosphorus-33 is a synthetic unstable isotope of P.
To find out the number of electrons in an element you must add the protons and neutrons and subtract that number with the atomic mass, this will determine the amount of electrons because the unknown element could be an isotope and have more than the normal amount of electrons of the non isotope element.

count the protons and neutrons
In order to answer this, the number of neutrons must also be known. Subtract the number of neutrons from the mass number and the result is the atomic number. mass no. - no. of neutrons = atomic number (no. of protons)
It is a Cesium isotope, with the atomic mass of 112.It could also be an ion depending on how many total electrons it has.
The number of electrons in any neutral atom is always the same as the atomic number of the atom, 16 in this instance.
