What element has 35 protons 45 neutrons?
BromineBromine has a mass number of 80 and 35 protons so 80-35 = 45 neutrons.
Which ion has 45 neutrons 36 electrons and 35 protons quizlet?
Bromine is an ion with a mass number of 80, 35 protons, 45 neutrons, 36 electrons, and -1 charge.
What is the name of the ion with 35 protons and 36 electrons?
Answer and Explanation: The chemical element that has 35 protons and 36 electrons is bromine.
What element has 36 electrons in an ion?
For example, the neutral bromine atom, with 35 protons and 35 electrons, can gain one electron to provide it with 36 electrons. This results in an anion with 35 protons, 36 electrons, and a 1− charge. It has the same number of electrons as atoms of the next noble gas, krypton, and is symbolized Br−.
How do you find an ion symbol?
Conventions for Writing Ions When writing the symbol for an ion, the one- or two-letter element symbol is written first, followed by a superscript. The superscript has the number of charges on the ion followed by a + (for positive ions or cations) or - (for negative ions or anions).
What is the charge of an ion that contains 35 protons and 36 electrons Express your answer as a signed integer?
Since there are 35 protons in the nucleus and each proton carries a charge of +1, the charge on the nucleus is +35. The 36 electrons, each with a charge of -1, combine to give a charge of -36. The net charge on the ion is the difference between the two: Ion charge = +35 - 36 = -1.
What is the mass number of an atom containing 35 protons 35 electrons and 44 neutrons?
The mass of the nuclide is 80⋅amu .

What is the symbol for an ion with 36 electrons and 48 neutrons?
#36 - Krypton - Kr.
What is the ionic charge of an ion with 38 protons and 36 electrons?
Explanation: The atomic number (38) is the number of protons. Since the charge on the ion is +2, we know there are two more protons than electrons. Hence 36 electrons.
Which isotope has 45 neutrons quizlet?
A selenium (Se) atom has 45 neutrons, 34 protons, and 34 electrons.
Which element contains 45 neutrons and 34 protons?
A selenium ion has 34 protons, 36 electrons, and 45 neutrons.
What is the charge on an ion that contains 34 protons 46 neutrons and 36 electrons?
Explanation: While the number nuclear protons as given is 34, and therefore we deal with the element selenium, there are 2 more electrons than protons, and therefore this species has an overall 2− charge.
How many electrons are in the P3 ions?
18 electronsPhosphorus has atomic number 15, it means that it has 15 protons as well as 15 electrons because atom is neutral. But, here we have P3- which means that this atom has gained 3 electrons. So, P3- has 18 electrons.
