This particle is the proton with a positive charge.
atomic number
The atomic number always equals to the number of protons. which in this case, is 20
There are similar number of electrons and protons. it has 15 electrons and protons.
In an atom, 10 protons and 10 electrons. (# of protons = atomic number) =)
valence electrons is the same as the number as the last digit in the group :)
Number protons equal to atomic number. So the element is Helium
An atom is neutral if the number of protons and the number of electrons it has are the same.
The number of electrons should equal the number of protons, otherwise you have an ion.
There are 50 electrons. In a neutral atom, the number of electrons equals the number of protons.
YES!!!!
Atoms that are neutral must have equal numbers of protons and electrons. This is because protons have a positive charge and electrons have a negative charge. Thus, for the charge to be neutral, the numbers of these particles must be equal.
The number of protons equals the number of electrons in an uncharged atom.
Yes
In a neutral atom, the number of electrons equals the number of protons. The number of protons is the atomic number of the element on the periodic table.
The atomic number of an element is the number of protons in its atoms. In a neutral atom, the number of protons equals the number of electrons.
neutral
2 * Z
In a neutral atom the number of electrons is equal to the number of protons. The opposite charge between protons and electrons is what allows for a neutral atom.
