Is it true that all atoms have the same number of protons?

The number of protons in an atom is called its atomic number (Z). This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.

Do all protons have the same mass True or false?

Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron.

Is all atoms are the same true or false?

Even if left alone, an atom often does not come with an equal number of protons and electrons. An atom of sodium from table salt behaves very differently from an atom of sodium from metallic sodium. In general, atoms of the same element are not identical as they can be in different states.

Do all atoms have the same number of neutrons and protons?

Neutrons are all identical to each other, just as protons are. Atoms of a particular element must have the same number of protons but can have different numbers of neutrons.

Are atoms made up of protons neutrons and electrons True or false?

Atoms are made of extremely tiny particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge.

Do all atoms have equal number of protons and electrons?

Atoms do not always contain the same number of electrons and protons, although this state is common. When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons).

Are all atoms same?

They are not the same at all. Every atom consists of three basic units protons, neutrons, and electrons and these units determine the physical and chemical properties of an atom and matter. But the presence of a different number of these units( protons, neutrons, and electrons) makes an atom unique from the other atom.

Is it true that there are equal numbers of protons and electrons in neutral atoms?

Fundamental Subatomic Particles The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

Why do atoms always contain the same number of electrons and protons?

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.

What is true about all atoms?

All atoms have at least one proton and one electron. That would describe a normal hydrogen atom. Atoms make up the elements so all elements are made of atoms. Most atoms will bond with at least one other atom but not all.
