RBC's (Red Blood Cells)only lose their nucleus when it and the organelles begin to mature. RBCS are known to lack a mitochondria, which it will depend on anaerobic fermentation to produce ATP.
This question is badly worded and is not even a question. I wish people would stop posting questions from their Biology and chemistry exams.
That said, the answer you're looking for is "white blood cell."
It is the White Blood Cell .... formal name Leokocyte :)
The smallest element on the Periodic Table is Hydrogen. It has only 1 electron in 1 electron shell and 1 proton in it's nucleus.
Elements are chemically defined by the number of protons present in the nucleus. The atomic number of an element is merely the number of protons that are in the nucleus. There are various isotopes of the same element, which just means the amount on neutrons has changed, however the protons remain the same.
It has the lowest atomic number (one) as its nucleus contains only one proton (and (usually) no neutrons).
isotopes have varying amounts of electrons ^ The above is wrong. Isotopes of an element vary in the amounts of neutrons within the nucleus only.
yes.fluorine is the most reactive element because it has a bigger nucleus,more protons that attract negative electrons and only has one full shell.
There is an isotope of hydrogen called 'protium', which only has 1 proton and 1 electron, with no neutron.
In a Hydrogen nucleus there is a proton. Hydrogen is the only element to not have a neutron in it's nucleus.
Hydrogen (atomic number 1) typically only has a single proton in its nucleus.

which element can only formed one ion
hudrogen
An element's atomic number is a count of how many protons are normally part of the element's nucleus. Since protons are normally the only particle in the nucleus with a charge (+), the atomic number also represents the charge of the nucleus.
It changes only the atomic mass.
The only true cell among the formed elements of blood is the white blood cell (leukocyte). Red blood cells (erythrocytes) and platelets (thrombocytes) are not considered true cells because they lack a nucleus and other organelles.
Isotopes of one particular element differ only in their number of neutrons in nucleus.

A glance at the periodic table will tell you that Beryllium, atomic #4, has 4 protons in its nucleus.
