The atomic number of an element tells us that atom's number of protons. If the atom is neutral, its number of protons is going to equal its number of electrons. Thus, we need only find the element with the atomic number of 39, which is yttrium.
Y-Yttrlum Atomic number is 39.

Element refers to atoms that have the same number of Protons.
protons and neutrons. atoms are not the smallest thing but protons are. protons are slightly smaller than neitrons. but are not simple sphere's.
All of them.
The atomic number of boron is 5, and since the atomic number of an element is the number of protons in the nuclei of its atoms, boron atoms have 5 protons in their nuclei.
Yttrium is the name of the chemical element that has exactly 39 protons in the nucleus of each of its atoms.
Protons are smaller than atoms. Protons are subatomic particles that are found within the nucleus of an atom along with neutrons. Atoms are made up of protons, neutrons, and electrons.
Protons are part of the nuclei of atoms. All matter has atoms therefore there are protons in batteries.
39 protons
All atoms with the same number of protons are atoms of the same element. The number of protons is the atomic number of the element.
Dinitrogen tetroxide has 2 nitrogen atoms and 3 oxygen atoms. Nitrogen has 7 protons and oxygen has 8 protons. So this compound has 38 protons.Oxygen atoms have eight protons each. Nitrogen atoms have seven protons each. So, the given compound has 7x2 + 8x4 = 46 protons.
Oxygen atoms contain protons like every other atoms. It has 8 protons in a atom.
Protons are protons, no matter what element they are in.
All atoms don't have the same number of Protons.
All atoms have neutrons, protons and electrons.
Sodium has 11 positively charged protons. (All atoms have positively charged protons, though they differ in hte number of protons).
An element can be identified by the number of protons in the nucleus of its atoms.
