FALSE!!!!
A neutral atom must have the same number of protons and electrons.
The number of neutrons can vary, to form isotopes.
When the number of protons and electrons are different, they are no longer atoms but IONS.
If we take hydrogen as an example, it forms three isotopes.
#1 ; protium ; 1 proton, 0 neutrons and 1 electrons
#2 ; deuterium ; 1 proton , 1 neutron and 1 electron
#3 ; tritium ; 1 proton , 2 neutrons and 1 electron
Notice the protons and electrons are the same number, but the number of neutrons varies, between isotopes.
False. A neutral atom needs the same number of protrons and electrons.
False, electrons are negatively charged whereas neutrons have no charge. An electron is of opposite charge to a proton which has a positive charge.
No. Protons are positive and neutrons are neutral. Protons have exactly the opposite charge as that of electrons, even though they differ greatly in mass. Proton is 1826 times heavier than electron.
No. The essence of an isotope is that all isotopes have the same number of protons in the nucleus, and thus the same number of electrons. What varies is the number of neutrons in the nucleus.
false they have the same number of protons, but varying numbers of neutrons
electrons and Protons
no. an atom is made up of protons neutrons and electrons. protons have a charge of plus one electrons have a charge of minus one neutrons have no charge. therefore the number of protons and electrons must be equal (balancing the charges) for the atom to be neutral. ;)
False. An atom is neutral if it has an equal number of protons and neutrons
False. The atom that has the same number of protons as it has electrons is a neutral atom.
false
False, electrons are negatively charged whereas neutrons have no charge. An electron is of opposite charge to a proton which has a positive charge.
False. Number of neutrons.
No. That would be called an ion.
No. Protons are positive and neutrons are neutral. Protons have exactly the opposite charge as that of electrons, even though they differ greatly in mass. Proton is 1826 times heavier than electron.
False as a generalization but true for some isotopes. The atomic number is the number of protons in a nucleus, which may coincidentally be the same as the number of neutrons but is not required to be.
No. The essence of an isotope is that all isotopes have the same number of protons in the nucleus, and thus the same number of electrons. What varies is the number of neutrons in the nucleus.
