What determines an element's charge?
The number of protons and electrons in the atom. If the number of protons = number of electrons, it is electrically neutral. If number of protons > number of electrons, it is positively charged. If number of protons < number of electrons, it is negatively charged.
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.
What are the number of protons neutrons and electrons in an element?
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - 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
How many electrons versus protons in an atom?
The number of electrons should = 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.
What tells you how many protons and electrons an element has?
The atomic number = Number of protons = Number of electrons
In a neutral atom the number of electrons equals the number of what?
The number of electrons should equal the number of protons, otherwise you have an ion.
How do you find the number of protons electrons of an element?
The atomic number of the element is the number of protons, therefore there has to be the same amount of electrons to protons.
How many electrons and protons are there in potassium?
A potassium atom has 19 protons and 19 electrons. This is because the number of protons in an atom is equal to its atomic number, which for potassium is 19. Electrons in a neutral atom are equal to the number of protons.
Is the number of valence electrons equal to the number of protons?
No, the number of valence electrons is not always equal to the number of protons. The number of valence electrons is determined by the group number of an element on the periodic table, while the number of protons is the atomic number of the element.
What is the number of protons in the necleus?
# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass
