Atoms of the same element always have the same number of protons, same Z, but often have different numbers of neutrons, therefore, different mass numbers. These atoms are called isotopes and are introduced in next section. The most common carbon atoms have six protons and six neutrons in their nuclei.Jun 29, 2021
What are always the same for atoms of the same elements?
Atoms of the same element have the same atomic number so the number of protons (and electrons) are same. But they have same or different mass numbers (like that for isotopes). Different mass number will have different number of neutrons. Was this answer helpful?
What do all atoms of the same element have in common quizlet?
Atoms of the same element all have the same number of protons but they can have different numbers of neutrons. This is why different atoms of the same element can have different atomic masses.
What do all atoms in the same group have in common?
The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
Are all atoms the same?
Everything in this world are matter and comprises of atoms. But each and every atom is unique. They are not the same at all. Every atom consists of three basic units protons, neutrons, and electrons and these units determine the physical and chemical properties of an atom and matter.
Do all atoms of the same element have?
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.
Do all atoms of the same element have the same atomic mass?
REMEMBER: 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. Most elements as they occur naturally on earth are mixtures of several isotopes.
Why do all atoms of an element have the same atomic number although they may have different mass numbers quizlet?
The number of protons in the nucleus of an atom; the atomic number is the same for all atoms of an element. Why do two isotopes of an element have the same atomic number but different mass numbers? Isotopes of an element have the same number of protons (the same atomic number), but have a different numbers of neutrons.
What do elements in same group have in common Why?
Elements in the same group have the same number of valence electrons, and therefore have similar levels of reactivity.
What do elements in the same group have in common What do elements in the same period have in common?
ll of the elements in a period have the same number of atomic orbitals. In other words they have the same number of valence electrons.
