What is an atom with unequal numbers of protons and neutrons called?

When an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION.

Do isotopes have a different number of neutrons and protons?

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 stable isotopes of nitrogen gizmo answer key?

What are the stable isotopes of nitrogen? nitrogen-15, carbon-14, nitrogen-14.

What makes an isotope?

Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table. For example, carbon has six protons and is atomic number 6.

When the proton and electron number are unequal?

is an ion When the proton number and electron number are unequal, the atom or molecule has a net positive (cation) or negative charge (anion). 11 The number of electrons will equal the number of protons in an electrically neutral atom.

What do you call particles having unequal number of electrons?

In the neutral atom, NECESSARILY there are equal number of protons, massive, charged nuclear particles, and electrons, mass-less, extra-nuclear particles of OPPOSITE charge to the nuclear charge. An excess OR deficiency of electrons results in an anion or cation given Z .

Why do isotopes have different neutrons?

Isotopes of an element are atoms with the same number of protons, but a different number of neutrons. Changing the number of neutrons in an atom changes that atom’s atomic mass. Each proton has a charge of +1, each electron a charge of -1, the neutrons have no charge (neutral charge–neutron).

Do different isotopes of the same element always have a different number of neutrons?

The different isotopes of an element have the same number of protons, as well as the same number of electrons. But the isotopes of an element always have different number of neutrons in their nuclei. The number of protons is also equal to that of electrons for an element.

Which particles are located in the nucleus gizmo answer key?

Gizmo Warm-up Atoms are tiny particles of matter that are made up of three particles: protons, neutrons, and electrons. The Element Builder Gizmo™ shows an atom with a single proton. The proton is located in the center of the atom, called the nucleus.

What substances make up water gizmo answer key?

Oxygen and Hydrogen are the substances that make up water.

What do isotope numbers mean?

: the number of neutrons minus the number of protons in an atomic nucleus.

What is a simple definition of an isotope?

An isotope is one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties. Every chemical element has one or more isotopes.

What is an isotope of an element?

Isotopes are formally defined as elements with the same number of protons, but a different number of neutrons in the nucleus. Another definition of isotopes defines them as atoms with the same atomic number (number of protons), but different atomic mass numbers (the sum of neutrons and protons of an atom).

What is the difference between isotopes and isotones and isbars?

Isotopes are nuclides having the same number of protons; compare: Isotones are nuclides having the same number of neutrons. N = A − Z {\\displaystyle N=A-Z}. Isobars are nuclides having the same mass number, i.e. sum of protons plus neutrons.

What is the difference between mass number and isotope number?

The number of nucleons (both protons and neutrons) in the nucleus is the atom’s mass number, and each isotope of a given element has a different mass number. For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively.

What are the neutron numbers of the isotopes of carbon-13?

The atomic number of carbon is 6, which means that every carbon atom has 6 protons so that the neutron numbers of these isotopes are 6, 7, and 8 respectively. A nuclide is a species of an atom with a specific number of protons and neutrons in the nucleus, for example carbon-13 with 6 protons and 7 neutrons.
