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.
What else can I help you with?
Is true or false electron and neutron have opposite charge?
False, electrons are negatively charged whereas neutrons have no charge. An electron is of opposite charge to a proton which has a positive charge.
Is it true or false that isotopes are forms of an element that have the same number of protons but a different number of electrons?
false they have the same number of protons, but varying numbers of neutrons
Do all isotopes of an elements have different numbers of electrons?
No, all isotopes of an element have the same number of protons (which determines the element's identity) and therefore the same number of electrons in a neutral atom. Isotopes differ in the number of neutrons they contain.
Is is true or fals neutrons repel each others?
False. Neutrons do not repel each other. They are electrically neutral particles that are held together within an atomic nucleus by the strong nuclear force, which overcomes their repulsion due to the electromagnetic force.
Do Protons have the same magnitude of charge as electrons but are opposite in sign?
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.
Is true or false electron and neutron have opposite charge?
False, electrons are negatively charged whereas neutrons have no charge. An electron is of opposite charge to a proton which has a positive charge.
A neutral atom has the same number of protons as it does neutrons?
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. ;)
Is an atom that has the same number of protons as neutrons a neutral atom?
False. The atom that has the same number of protons as it has electrons is a neutral atom.
Are the number of neutrons equal to the atomic number minus the atomic mass?
false
Is an atom neutral if it has a greater number of electrons than protons?
False. An atom is neutral if it has an equal number of protons and neutrons
The atomic number of isotopes is determined by the number of atoms. true or false?
False. Number of neutrons.
The number of neutrons is equal to the atomic number true or false?
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.
Is it true or false that isotopes are forms of an element that have the same number of protons but a different number of electrons?
false they have the same number of protons, but varying numbers of neutrons
Do all isotopes of an elements have different numbers of electrons?
No, all isotopes of an element have the same number of protons (which determines the element's identity) and therefore the same number of electrons in a neutral atom. Isotopes differ in the number of neutrons they contain.
Can new elements be made by changing the number of neutrons in an atom?
false
CAN New elements can be made by changing the number of neutrons in an atom.?
false
True or false The number of neutrons is equal to the atomic number?
False. The number of neutrons is not equal to the atomic number. Neutrons are particles found in the nucleus of an atom and their number can vary, whereas the atomic number corresponds to the number of protons in an atom.
