Quick Answer: What Is Another Word Meaning Having The Same Number Of Protons In Its Nucleus?

What are the same number of protons called?

Isotopes are atoms of the same element (same number of protons) that have different numbers of neutrons in their atomic nuclei.

What is the number of protons in the nucleus called?

The number of protons in the nucleus of an atom is called its atomic number: the atoms of a particular element all have the same number of protons. the atoms of different elements have different numbers of protons.

What is isotope mean?

isotope, 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 behaviour but with different atomic masses and physical properties. Every chemical element has one or more isotopes.

What do we call nuclei that all have the same number of protons?

In an electrically neutral atom, the number of protons equals the number of electrons. Isotopes of an element have the same number of protons but have different numbers of neutrons in their nuclei. The mass number is the sum of the numbers of protons and neutrons in the nucleus of an atom.

Which two has the same mass number?

Two atoms with the same atomic number, but different mass numbers (same number of protons, different number of neutrons), are called isotopes, or isotopic nuclides. Having different numbers of neutrons changes the mass of these atoms, so isotopes have slight variations in their physical and chemical behavior.

Can two elements have the same number of protons?

Explanation: Atoms from two different elements may have the same number of neutrons, but never the same number of protons. The number of protons is unique to the element and represents the atomic number.

Which subatomic particle is the lightest?

Electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 1019 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 1031 kg, which is only 1/1,836the mass of a proton.

Why is nucleus positively charged?

The nucleus has an overall positive charge as it contains the protons. Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.

Who discovered the proton?

It is 100 years since Ernest Rutherford published his results proving the existence of the proton.

What are 2 examples of isotopes?

For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively. 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.

What is an isotope in your own words?

isotope Add to list Share. An isotope of a chemical element is an atom that has a different number of neutrons (that is, a greater or lesser atomic mass) than the standard for that element. The atomic number is the number of protons in an atom’s nucleus.

What is isotope give an example?

Isotopes can be defined as the variants of chemical elements that possess the same number of protons and electrons, but a different number of neutrons. For example, carbon-14, carbon-13, and carbon-12 are all isotopes of carbon.

Which two nuclei contain the same number of neutrons?

Isotone, any of two or more species of atoms or nuclei that have the same number of neutrons. Thus, chlorine-37 and potassium-39 are isotones, because the nucleus of this species of chlorine consists of 17 protons and 20 neutrons, whereas the nucleus of this species of potassium contains 19 protons and 20 neutrons.

What makes each element unique?

Each element has its own unique properties. Each contains a different number of protons and neutrons, giving it its own atomic number and mass number. The atomic number of an element is equal to the number of protons that element contains.

What do all atoms have the same number of?

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.
