What is the same for atoms of the same element?

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.

Are all atoms of the same element are alike?

No. Two atoms of the same chemical element are typically not identical. First of all, there is a range of possible states that the electrons of an atom can occupy. Two atoms of the same element can be different if their electrons are in different states.

What similarity do atoms of the same element share?

All atoms of the same element have the same number of protons, but some may have different numbers of neutrons. For example, all carbon atoms have six protons, and most have six neutrons as well.

What do the same elements have in common?

Elements in the same group have the same number of valence electrons, and therefore have similar levels of reactivity. Every element is made of only one type of atom, and that atom has a unique number of protons, with varying numbers of neutrons and electrons.

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.

Do all elements have same number of protons and electrons?

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).

How are atoms and elements alike?

How are atoms and elements related? An atom is the basic unit of life, and an element is one type of atom, or a group of the same type of atoms. All atoms of the same element have the same number of protons. Atoms of different elements differ in the number of protons.

Why are atoms of elements the same?

All atoms of the same element have the same number of protons, but some may have different numbers of neutrons. For example, all carbon atoms have six protons, and most have six neutrons as well.

Do all atoms of the same element have the same number of neutrons?

No, the same element may contain different numbers of neutrons. These variants are called isotopes. For example, hydrogen has several isotopes.

What do all atoms of an element have in common?

What makes atoms of different elements different? The fundamental characteristic that all atoms of the same element share is the number of protons. All atoms of hydrogen have one and only one proton in the nucleus; all atoms of iron have 26 protons in the nucleus.

Who said atoms of the same element are identical?

Modern Atomic Theory (John Dalton) 2. All atoms of an element are identical. 3. Atoms of different elements have different weights and different chemical properties.

What do elements in the same group have in common quizlet?

What do elements in the same group have in common? They have similar chemical properties and the same number of valence electrons.

Do atoms of the same element have the same number of protons?

The number of protons in an atom is called its atomic number (Z). 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.

Do atoms of the same element have the same atomic number?

All atoms of a chemical element have the same atomic number (number of protons in the nucleus) but may have different mass numbers (from having different numbers of neutrons in the nucleus). Atoms of an element with the same mass number make up an isotope of the element.

Are all elements identical?

each element is made up of identical particles of matter called atoms. all the atoms in a pure substance or element are identical to one another but different to the atoms in a different element.

Are protons and electrons same?

Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom’s nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they are neutral).

What is an element related to an atom?

An atom is the part of an element. A particular element is composed of only one type of atom. Atoms are further composed of subatomic particles called electrons, protons and neutrons. Elements can combine with each other to form molecules via chemical reaction.

How must Two atoms of the same element always be the same?

Atoms of same element must have same number of protons, same number of electrons but may also have same or different number of neutrons (in case of isotopes). Was this answer helpful?

Are all protons the same?

Protons and neutrons are made of smaller “particles” called quarks. However, all protons are identical to each other, regardless of which element they are a part of. So, every proton is made of the same combination of 3 quarks.

Do all atoms of the same element have the same size?

Colm – So Les all atoms of the same material are the same size but different items of different materials are different sizes. So for instance the single smallest item is hydrogen and a single hydrogen is about one twentieth of a nanometre across.

What do all elements have?

Elements are made of the same types of atoms. Each atom is made of protons, neutrons, and electrons. Protons and neutrons are positioned in the center of the atom called the nucleus, and electrons are found in the outer portions of the atom called energy levels, or electron orbitals.

Who proposed that not all atoms of the same element were identical?

In the third part of Dalton’s atomic theory, he proposed that compounds are combinations of two or more different types of atoms.

Which two atoms are isotopes of the same element?

1. Basic principles. Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.

What are the difference among the same element?

Different isotopes of the same elements have the same atomic number. They have the same number of protons. The atomic number is decided by the number of protons. Isotopes have different mass number, though because they have different number of neutrons.

Why do elements in the same group have similar properties quizlet?

Elements in the same group have similar properties because they have the same number electrons in their outermost shell.
