Can two different elements have the same number of electrons?

Basically no two elements have same atomic number. Same number of protons and electrons are present in atoms which are in ground state. Example: Li is the third element in the periodic table, it’s atomic number is same as it’s number of electrons and protons which is 3.

Can two atoms of different elements have the same atomic number?

Explanation: Atoms from two different elements may have the same number of neutrons, but never the same number of protons. The number of protons is unique to the element and represents the atomic number.

Can atoms of different elements have the same number of valence electrons?

The number of valence electrons in an atom is reflected by its position in the periodic table of the elements (see the periodic table in the Figure below). Within each column, or group, of the table, all the elements have the same number of valence electrons.

Can the neutral atom of 2 different elements have the same number of electrons?

It is possible for atoms of different elements to have the same number of electrons. The number of neutrons in a neutral atom must always equal the number of protons.

Why can atoms of two different element have the same mass number but not the same atomic number?

Atoms of the same chemical element do not always have the same mass because, although the number of protons in the nucleus is the same for all atoms of the same element, the number of neutrons is not.

Why are atoms of different elements different?

The number of protons in an atom is the defining feature of an atom. It’s what makes one element different from another. The number of protons in an atom is called its atomic number. All the elements in the universe are arranged according to their atomic number in the periodic table.

How are atoms of different elements different?

Normally, the number of electrons is equal to the number of protons, which makes atoms electrically neutral. The number of protons in an atom is the defining feature of an atom. It’s what makes one element different from another. The number of protons in an atom is called its atomic number.

Can atoms of different elements have the same number of protons?

This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms. For example, all helium atoms have two protons, and no other elements have atoms with two protons.

Which 2 elements have the same number of valence electrons?

Therefore, two elements in the same group will have the same number of valence electrons. Since all bonding and/or ionizations involve the valence shell of electrons, atoms with the same number of valence electrons behave similarly. Both tellurium and sulfur are in group VI, and have 6 valence electrons.

Are all atoms the same element?

No. Although two such atoms are essentially chemically identical (they will chemically react in the same way), they are not completely identical. The nucleus of an atom contains neutrons and protons bonded tightly together. The same chemical element can have a different number of neutrons and still be the same element.

Can atoms of different elements have the same mass?

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).

Can atoms have different atomic masses?

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.

Do all atoms have the same number of electrons and protons?

Atoms do not always contain the same number of electrons and protons, although this state is common. When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). Click to see full answer.

Can two elements have the same atomic number?

Properties of elements depend upon their atomic numbers (modern periodic law). Therefore any two atoms which are having same number of protons and electron are having same properties. It follows that the two atoms belong to same element. Therefore, 2 elements can never have same atomic number.

Can two neutral atoms have the same number of electrons?

In a very strict sense, two neutral atoms belong to two different element could not have same number of electrons (because no two or more elements could have same number of protons [atomic number] ). but in general sense ions could have same number of electrons for example in the following species all have same number of electrons.

Can isotopes of the same element have different number of neutrons?

Atoms of the same element can have a different number of neutrons. These atoms are called isotopes, which are atoms of the same element that have a different number of neutrons. Subsequently, question is, can isotopes have different number of electrons? The atoms of a chemical element can exist in different types.
