What else can I help you with?
Are valence electrons the number of protons?
Only for hydrogen and helium are these two numbers the same. All other elements have at least two non-valence electrons, and the total number of electrons must be equal to the number of protons. Therefore, in all elements except hydrogen and helium, the number of valence electrons is less than the number of protons.
The number of these is equal to the number of electrons in an atom?
A neutral atom has equal numbers of elecrons and protons.
Are protons and electrons always equal?
yes,,,because the number of protons is equal to the number of electrons. No, when electons are lost or gained by an atom (number of protons stays the same) the atoms become 'ions,' which are positively or negatively charged respectively.
Most atoms have equal numbers of?
an atom has a no charge or has a net charge zero as it contains equal number of electrons and protons .for example a sodium atom Na has 11 protons and 11 electrons .mathematically +11_11 =0 hence no charge .
In a neutral atom what is the relationship between the number of protons and electrons?
They are equal.
Why elements have different number of electrons?
In a neutral atom the number of electrons is equal to the number of protons; and the number of protons is the label of a chemical element.
Equal to the number of protons in an atom found on the periodic table?
The atomic number or the number of electrons is equal to the number of protons.
What subatomic particle is always equal in neutral atoms?
protons and electrons will always be = number
What must be equal in a neutral atom?
Protons and electrons must be equal in a neutral atom because protons and electrons have equal but opposite charges.
Is the number of protons no of electrons?
Yes , the no. of electrons is equal to the no. of protons
Are valence electrons the number of protons?
Only for hydrogen and helium are these two numbers the same. All other elements have at least two non-valence electrons, and the total number of electrons must be equal to the number of protons. Therefore, in all elements except hydrogen and helium, the number of valence electrons is less than the number of protons.
If an atom contains 15 electrons it will also have 15?
Protons, because electrons are equal to the atomic number and protons are equal to the number of electrons.
When atoms are at rest what do they have an equal number of?
protons and electrons protons and electrons
How are elements described in terms of the atoms?
Each chemical element has atoms with a specific number of protons, different from the atoms of other elements.
How many electrons versus protons in an atom?
The number of electrons should = the number of protons.
Do protons and electrons have the same number?
Yes, the atomic number is equal to the number of protons. The number of protons is also equal to the number of electrons
Nobelium has an atomic number of 102 how many protons and electrons does it have?
Nobelium has 102 protons and 102 electrons, as the number of protons is equal to the atomic number, and in a neutral atom, the number of protons is equal to the number of electrons.
