That totally depends on the number of protons in the substance. You could have a neutral Lithium atom (3 protons, 3 electrons), a positively charged Berryllium atom (4 protons, 3 electrons), a +2 Boron atom (5 protons, 3 electrons), etc. The higher you go in the Periodic Table the less likely you are to find the atom stripped down to just three electrons, but under extreme circumstances it is possible to do so - for example a Copper atom with only three electrons would have a charge of +26. In theory it might be possible to have a Hydrogen atom with two extra electrons or a Helium atom with one giving them a -2 or -1 charge, but those would probably be very difficult to achieve.
Other than individual atoms, you'd be hard pressed to find a substance with only three electrons, but in theory you could also have small molecules (i.e. H2) with a temporary extra electron, or small groups of metallic atoms that have lost all but three electrons, or even an "electron gas" that consists of nothing but three isolated electrons (in a magnetic trap). The charge for any of those would again depend on the number of protons involved (-1 charge for H2 with an extra electron, +3 for two Li atoms missing three electrons, -3 for the isolated electrons).
By definition, every atom of every element must have the same number of protons as every atom of that same element. So, all you have to do is find which element has 35 protons. Look at the periodic table, and find the 35th listed element. That element is Bromine. So Bromine is the correct answer.
The particle with a -3 charge and 36 electrons is an ion of the element phosphorus (P). It has gained three extra electrons, resulting in a charge of -3.
The net charge will be negative, since electrons have a negative charge and protons have a positive charge. When 5 electrons (-5) combine with 3 protons (+3), the net charge will be -2.
The element with 15 protons and 16 neutrons is phosphorus (atomic number 15). The net charge of negative 3 means it has gained 3 electrons, making it an ion of phosphorus with a charge of -3.
the nucleus always has a positive charge. The atom on the other hand in its singular state will have no charge as the electrons negative charge counter the protons positive charge. in this example there will be 31 electrons The element would be Gallium but there are not enough neutrons in your question to even make a viable isotope. Gallium typically has 31 protons and 39 neutrons
The element with 24 protons is Chromium (symbol Cr) and a charge of +3 means it has lost 3 electrons, making it a cation with a +3 charge.
The element is vanadium (V) because it has 23 protons. With 18 electrons and a net charge of 3 plus, it would have lost 3 electrons, resulting in a net charge of +3. The number of neutrons (28) does not affect the charge or identity of the element.

Atomic Number: This is the number of protons an element has. Answer: 26 Atomic Mass: Ignoring electrons, which are incredibly small and don't have much of an effect on the mass... This is the number of protons plus the number of neutrons Answer: 56 (26 protons + 30 neutrons) Net Charge: Protons are positive and electrons are negative. The net charge can be found by subtracting the number of electrons from the number of protons. 0 is neutral. Answer: +3 (26 protons - 23 electrons)
The element lithium has 3 protons and 3 electrons.
The net charge will be negative, since electrons have a negative charge and protons have a positive charge. When 5 electrons (-5) combine with 3 protons (+3), the net charge will be -2.
The element with 15 protons and 16 neutrons is phosphorus (atomic number 15). The net charge of negative 3 means it has gained 3 electrons, making it an ion of phosphorus with a charge of -3.
Atoms are made up of three types of particles: protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. The number of protons determines the element of the atom, while the number of neutrons and electrons can vary.
It has 3 more protons than electrons. Protons are 1+ and electrons are 1-. So the charge on the hypothetical ion would be 3+
Electrons have a -1 charge while protons have a +1 charge. Thus, subtracting the number of electrons from the number of protons gives the charge of a species. For example, if a lithium ion has 3 protons and 2 electrons, it has a +1 charge.
In Li plus 1, the element is lithium (Li) which has 3 protons. Since it has a +1 charge, it means it has lost one electron, so it has 2 electrons.
