Verified step by step guidance1
Identify the atomic number of the element, which is given as 44. The atomic number represents the number of protons in the nucleus of an atom.
Recall that in a neutral atom, the number of electrons equals the number of protons to balance the positive charge of protons with the negative charge of electrons.
Therefore, for an element with atomic number 44, the number of protons is 44.
Since the atom is neutral, the number of electrons must also be 44 to balance the charge.
Conclude that a neutral atom of the element with atomic number 44 has 44 protons and 44 electrons.
