What is different about these two atoms?

What is different about these two atoms?

Two atoms of the same element can be different if their electrons are in different states. If one copper atom has an electron in an excited state and another copper atom has all of its electrons in the ground state, then the two atoms are different.

What does 2 atoms mean?

Diatomic molecules are molecules composed of only two atoms, of the same or different chemical elements. The prefix di- is of Greek origin, meaning “two”. If a diatomic molecule consists of two atoms of the same element, such as hydrogen (H2) or oxygen (O2), then it is said to be homonuclear.

What can you conclude about two atoms with different proton counts?

If two atoms have different numbers of protons, they are different elements.

What 2 are inside the atom?

The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside.

What is it called when two atoms of the same element have a different number of neutrons?

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 information would allow you to determine whether two atoms are of the same or different elements?

Atomic Number and Mass The number of protons determines an element’s atomic number and is used to distinguish one element from another. The number of neutrons is variable, resulting in isotopes, which are different forms of the same atom that vary only in the number of neutrons they possess.

How do you know if two atoms are the same element?

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. We refer to the atoms of the same element with different numbers of neutrons as “isotopes”.

What does an atom share when it bonds with another atom?

Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.

What can you conclude about two atoms with the same protons?

Two atoms have the same number of protons but different numbers of neutrons. What can you conclude about these two atoms? That they are isotopes, i.e. the same element, but different atomic masses. The number of nuclear protons gives Z, the atomic number.

Can two atoms have the same atomic number but different mass numbers?

Two atoms having the same number of protons but different numbers of neutrons will have same atomic number but different mass number.Thus they are isotopes of the same element. As Atomic number = Number of protons.

Which pair of atoms are isotopes of the same element?

Since the two atoms have the same number of protons they are the same element. The fact that they have different numbers of neutrons makes them isotopes. The best answer is A.

What are the similarities between the elements A and B?

A-they are the same element B-they are the same isotope C-they have the same mass D-thay have the same charge. Since the two atoms have the same number of protons they are the same element. The fact that they have different numbers of neutrons makes them isotopes.
