Do isotopes have the same number of protons and electrons?

Answer 1

YES!!!

The difinitive answer is ' Isotopes of an element have a DIFFERENT number of neutrons'.

Takinf an example. The element Hydrogen .

It has three isotopes. They are: -

#1 ; protium ; 1 proton , 0 neutrons, 1 electron ; Atomic Mass '1'

#2 ; deuterium ; 1 proton , 1 neutron , 1 electron ; Atomic mass '2'

#3 ; tritium ; 1 proton 2 neutrons 1 electron. 'Atomic mass '3',

Carbon also has three isotopes biz.,

# 1 ; Carbon-12 ; 6 protons, 6 neutroins, 6 electrons ;Atomic mass '12'

#2 ; Carbon-13 ; 6 protons, 7 neutroins, 6 electrons ; Atomic mass ''13'

#3 ; Carbon-14 ; 6 protons, 8 neutroins, 6 electrons ; Atomic mass '14'.

Notice in each case the number of neutrons changes, the number of protons remains the same, otherwise it is a different element. The Atomic mass is the sum of the protons and neutrons.

NNB Every element has isotopes.

NNNN Do not confuse 'Isotopes' with 'Allotropes'. Allotropes are elements exhibiting a different physical form/appearance.

Answer 2

Yes, isotopes have the same number of protons (which determines the element) but different numbers of neutrons. The number of protons in an atom is what defines its element, while isotopes of an element have the same number of electrons, maintaining the element's chemical properties.

Answer 3

Yes. Different isotopes of an element always have the same number of protons because the number of protons determines the elemental identity of the substance. It is the number of neutrons that changes to make up the different isotopes of a given element.

Answer 4

The answer is no, isotopes must have the same number of protons, but they can have varying numbers of neutrons. You will notice some isotopes have the same atomic mass number, but if you look at their atomic number, you will see that it is different. That is because atomic numbers shows you how many protons there are. Mass number shows the total number of nucleons. If you change the number of protons, you get a different element.

Answer 5

Yes, they do. While they have a different mass number due to a difference in the number of neutrons, they have the same atomic number. The atomic number is what determines the number of protons. Therefore, they all have the same number of protons. Also, they have the same number of electrons as well. The only thing that differs is the number of neutrons.

An example of some isotopes of carbon include Carbon-12, Carbon-13 and Carbon-14. The 12, 13, and 14 denote their mass numbers. Carbon's atomic number is 6, so each isotope has 6 protons while the number of neutrons varies. For example, Carbon-12 has 6 neutrons because 12-6=6. Meanwhile, Carbon-13 has 7 neutrons because 13-6=7.

Answer 6

Exactly. That is how elements are defined, by their number of protons.

Answer 7

Yes, the number of protons defines the element.

Answer 8

One isotope of an element may have the same number of either neutrons or protons, but not both; in that case they would be the same isotope.

Answer 9

Yes. because isotopes onyl have different number of neutrons but not protons and therefore, number of electrons will also remain same as NUMBER OF ELECTRONS=NUMBER OF PROTONS

Answer 10

Yes. Only the number of neutrons differs.
