Is the atomic number of an atom equal to the number of protons or neutrons or electrons in the nucleus?
The atomic number of an atom is equal to the number of protons in the nucleus. It determines the element's identity and position on the periodic table. Electrons and neutrons can vary in number to form different isotopes of the element.
How many protons electrons and neutrons in the element kalsium?
1) it's spelt Calcium and 2) 20 protons, 20 electrons, 20 neutrons
Can you use the mass number of an element to determine the number of electrons in an atom?
No, the mass number of an element is the sum of protons and neutrons in the nucleus. To determine the number of electrons, you would need to know the atomic number of the element, which is equal to the number of protons. Electrons in a neutral atom equal the number of protons.
What is the number of protons neutrons and electrons of carbon 12?
Carbon-12 has 6 protons, 6 neutrons, and 6 electrons. The number of protons determines the element (carbon), the number of neutrons plus protons gives the mass number (12), and in a neutral atom, the number of electrons equals the number of protons.
How do two isotopes of an element are similar?
They have the same number of protons in the nucleus and same number of electrons surrounding the nucleus.
What element contains 74 protons 74 electrons and 109 neutrons?
The element with 74 protons is tungsten (symbol W). The number of electrons and neutrons does not affect the identity of the element, which is solely determined by the number of protons.
How many protons neutrons and electrons are in elements?
The number of protons in an element is its atomic number, which determines its identity. Neutrons can vary for different isotopes of the same element. Electrons equal the number of protons in a neutral atom.
Why doesnt the number of protons change for a single element while the neutrons and electrons can?
The number of protons in an atom determines its identity as a specific element. Changing the number of protons would change the element. Neutrons and electrons can be added or removed without changing the identity of the element since they do not affect the element's chemical properties.
Does an atom retain the chemical identity of an element?
An isotope is an atom that contains a different number of neutrons. In order for an element to change there has to be a different number of protons.
What subatomic particle helps identify the element's identity?
There is no individual sub-atomic particle that is responsible for the identity of an element. It is the way the electrons, protons and (neutrons) are arranged in an element that gives it it's identity.
Is boron protons electrons or neutrons?
Boron is an atom or element, and it contains protons, electrons, and neutrons.
What was the atom made of?
An atom is made up of a nucleus containing protons and neutrons, with electrons orbiting around the nucleus. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. The number of protons determines the element's identity.
Protons electrons and neutrons in any given atom?
The atomic number of a chemical element is equal to the number of electrons or protons. The number of neutrons = Atomic weight of an isotope (rounded) - atomic number of the element (or the number of protons)
How many protons neutrons and electrons are in the element manganese?
Manganese has 25 protons, 25 electrons and 30 neutrons.
What is element in building?
Protons, Neutrons, and Electrons
Atomic masses of any two elements contain the same number of?
protons and neutrons. This is because the atomic mass of an element is calculated by adding the number of protons and neutrons in the nucleus of an atom. The number of protons determines the element's identity, while the number of neutrons affects its stability.
Which element determines the identity of an element?
The number of protons in the nucleus determines what element it is. There can be different isotopes that have more or less neutrons, and there can be ions meaning they're positively or negatively charged which means they've lost an electron or gained an extra one.
