Usually, an atom has the same number of protons as electrons, but when the number of electrons is changed, the atom is considered ionic. An atom that has lost an electron is called an anion, and an atom that has gained an electron is called a cation. One example of a cation is a potassium ion, or K+, and one example of an anion is chloride,(a chlorine ion) or Cl-
The neutral atom of an element has a different number of electrons, compared to the ion of this element.
An atom of an element that has a different number of electrons is called an ION.
In the neutral state, all atoms of the same element contain equal numbers of protons and electrons. However, most elements have atoms with different numbers of neutrons. These are called isotopes.
Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.
The isotopes of an element are alike in that they have the same number of protons, electrons, and the same chemical properties. The isotopes are different in that they have different numbers of neutrons and thus different atomic masses.
Hydrogen is an element, and the smallest form of an element is an atom. If you meant electrons, then 1.
They all have the same number of neutrons. All atoms of a given element have a specific number of protons. That is what gives an element its elemental identity. But we know that different atoms of a given element can have different numbers of neutrons. These different atoms of the same element are the isotopes of that element. All the atoms of a given isotope of a given element will have the same number of protons and will have the same number of neutrons. all isotopes of an atom have same number of proton but they have different number of neutron so they have same chemical properties and different physical properties. all isotopes of an atom have same number of proton but they have different number of neutron so they have same chemical properties and different physical properties.
All atoms of an element contain the same number of electrons and protons but they can have different numbers of neutrons. Atoms with different numbers of neutrons are isotopes.
In the neutral state, all atoms of the same element contain equal numbers of protons and electrons. However, most elements have atoms with different numbers of neutrons. These are called isotopes.
An atom with a different number of electrons is called an ion.
Isotopes have the same number of protons an electrons; the number of neutrons is different.
The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.
Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.
Isotopes are atoms of an element having different number of electrons.
All atoms of the same element contain the same number of protons and electrons, but atoms of a given element may have different numbers of neutrons. Atoms with the same number of protons but different numbers of neutrons are called isotopes. An element has many isotopes--each with a close, but different number of neutrons.
They have different numbers of neutrons. An element is all of the atoms that have the same number of protons, but the the number of neutrons and electrons may vary.
Every atom of one element has different no. of electrons than any atom of any other element.
Neutral isotopes are atoms of the same element which have the same number of protons and electrons, but different numbers of neutrons.
The isotopes of an element are alike in that they have the same number of protons, electrons, and the same chemical properties. The isotopes are different in that they have different numbers of neutrons and thus different atomic masses.
