What two elements have the same number of electrons?

Electrons

Atomic Number	Element	Energy Levels or “shells”
9	Fluorine (F)	7
10	Neon (Ne)	8
11	Sodium (Na)	8
12	Magnesium (Mg)	8

Which atoms have the same number of electrons?

Atoms having the same number of protons (and therefore the same number of electrons) but different numbers of neutrons are called isotopes of the element in question. Thus, the isotopes of an element have the same atomic number but differ in their atomic mass number.

What two atoms have the same number?

Two atoms with the same atomic number, but different mass numbers (same number of protons, different number of neutrons), are called isotopes, or isotopic nuclides.

Do any elements have the same number of electrons?

In all electrically-neutral atoms, the number of electrons is the same as the number of protons. Each element, when electrically neutral, has a number of electrons equal to its atomic number.

Can two different atoms of different elements have the same electron configuration?

Every element has a unique atomic number and therefore a unique number of electrons in its unionized elemental form. You can’t have the same electron configuration with different numbers of electrons.

Can two elements have same electron configuration?

When two different elements have the same electron configuration, they are called isoelectronic.

Do atoms have the same number of electrons and neutrons?

The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

Which two atoms have the same number of neutrons?

Isotones and isobars have great significance for studying of nuclide stability. Two nuclides (a type of a nucleus with some values of Z and N) that have the same number of neutrons N have the same number of neutrons.

Which 2 atoms have the same mass number?

Atoms of an element with the same mass number make up an isotope of the element. Different isotopes of the same element cannot have the same mass number, but isotopes of different elements often do have the same mass number, e.g., carbon-14 (6 protons and 8 neutrons) and nitrogen-14 (7 protons and 7 neutrons).

What is the same for all atoms of the same element?

All atoms of the same element have the same number of protons in their nucleus.

How are atoms of the same element the same How are atoms of the same element different?

ISOTOPES AND ATOMIC MASSES For many of the chemical elements there are several known isotopes. Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.
