The atomic number, or Z, is the number of protons in the nucleus of an atom of an element. This is what determines what element an atom is. A link can be found below.
Z= number of protons (posetive)= number of electrons (negative)= atomic number
lol easy
43
16 protons and 18 electron
a negative ion means that an electron(s) has been gained. therefore, there will be a higher number of electrons than protons, as the number of protons will not change
calcium
subtract the number of protons from the number of electrons. The above answer does not answer the question!!
count the number of protons which will be equal to number of electron.
43
16 protons and 18 electron
Atomic number = Number of protons = Number of electrons
electron
The number of protons.
no of the protons or the no of electron is equal to the atomic no denoted by the symbol Z
Atomic number is the equivalent of the number of protons in an atomic nucleus.
a negative ion means that an electron(s) has been gained. therefore, there will be a higher number of electrons than protons, as the number of protons will not change
Judging from its atomic number, indium has 49 protons and 49 electrons.
mass number = protons + nuetrons
Is the number of protons or electron found in a given (neutral) element.
