What can be said of the number of electrons of the one element can have?
A neutral atom of an element will have the same number of electrons as protons (atomic number). For example, the element magnesium has the atomic number 12, which means that a neutral magnesium atom will have 12 protons and 12 electrons.
What is the number protons in the nucleus?
The number of protons in the nucleus is equal to the atomic number of that atom. Said another way, the atomic number of any element is the number of protons in the nucleus of any atom of that element.It might be helpful to consider some examples, and if we look at mercury, we'll see it has an atomic number of 80. All atoms of mercury have 80 protons in them. Aluminum has the atomic number of 13, so all atoms of it have 13 protons in them. Uranium, which has atomic number 92, has 92 protons in all of its atoms.The number of electrons and neutrons in a given atom of a given element can vary for a number of reasons, and these characteristics are considered separately. The number of electrons in any atom will match the number of protons in the nucleus of that atom only if the atom is a neutral one. Some atoms loan out or borrow electrons, and then they become what are called ions. The number of neutrons can vary, too, and we use the term isotope to talk about atoms of a given element having different neutron counts.The atomic number indicates the number of protons in an atom's nucleus.The number of protons in the nucleus is the atomic number of the atom.
How many electrons are lost or gained in the element o when they form ions?
atoms gain and lose electrons, so they can have a full outer shell of 8 electrons (or two electrons if its the innermost shell) when atoms lose electrons it is called oxidation and when they gain electrons they are said to be reduced. OIL RIG is most commonly used to help remember that oxidation is loss and reduction is gain of electons. when atoms lose electrons they are left with a positive charge and when they can electrons they have a negative charge.
What is the difference between an atom and element?
Atoms are the building blocks of everything; they are made up of neutrons, protons, and electrons (and recently it has been discovered that these 3 things are made of quarks). Each atom is one piece on its own, floating around and attaching to other atoms.An element is a substance that is made up of only one type of atom. Once the atoms cling to each other they form different substances; if only one type of atom (which means that all atoms have the same number of electrons) is combined then it forms an element. If multiple different atoms cling together it forms other substances.Ex) When atoms with only 1 electron gather they form the element HydrogenWhen atoms with 8 electrons gather they form the element OxygenWhen 2 atoms with only 1 electron cling to one atom with 8 electrons, you end up with 2 Hydrogen atoms that have now mixed with 1 oxygen atom which forms the compound H2O or water; this compound (water) is no longer an element.
What can be said about the of neutrons that atoms of one element have?
The number of neutrons in the atoms of a specific element can vary, leading to the formation of isotopes. While all atoms of a given element have the same number of protons (defining the element), the neutron count can differ, affecting the atomic mass and stability of the isotopes. For example, carbon typically has six neutrons, but carbon-14, an isotope of carbon, has eight neutrons. These variations can influence the element's properties and behavior in chemical reactions.
What can be said of the number of electrons of the one element can have?
A neutral atom of an element will have the same number of electrons as protons (atomic number). For example, the element magnesium has the atomic number 12, which means that a neutral magnesium atom will have 12 protons and 12 electrons.
What subatomic particles can differ between neutral atoms of the same element?
Neutral atoms of the same element can differ in the number of neutrons, which results in different isotopes of the same element. Isotopes have the same number of protons and electrons, but different numbers of neutrons.
What does an elements atomic number represent-?
The number of protons (or electrons) an atom has. To find out how many neutrons there are take the atomic number and subtract it from the Atomic Mass... (atomic mass)-(atomic number)= neutrons atomic number= #of protons (or #of electrons)
What are atoms of different elements said to be called?
No. Atoms are what make up elements, so they don't count.
What is the difference between elements and atoms?
An atom is the smallest piece of an element. Said another way, and element is made up one and only one kind of atoms.
What is the number protons in the nucleus?

What was the point of Dalton atomic theory which is incorrect?
He said that atoms were indivisible, and we now know is not true because atoms are composed of protons, electrons, and neutrons, and that protons and neutrons are themselves composed of smaller particles. He also said that all of the atoms of the same element have the same mass, which we now know is not true because of the existence of isotopes.
What does an atom represent?
The atomic number is the number of protons in the nucleus. Neutral atoms contain the same number of electrons as protons to balance the electrostatic charge. The number of electrons on an atom will determine its charge, loss of electron(s) will make it positive, gain will make it negative. This occurs when atoms form ions.
What is the element of atoms?
Atoms are composed of subatomic particles: protons and neutrons in the nucleus, surrounded by electrons in orbitals. Protons have a positive charge, neutrons are neutral, and electrons have a negative charge. The number of protons in the nucleus determines the element's identity.
When atoms in a covalent bond share electrons equally the bond is said be?
When atoms in a covalent bond share electrons equally, the bond is said to be nonpolar covalent. This means that the atoms have similar electronegativities, resulting in a symmetrical distribution of electrons between them.
How many electrons are lost or gained in the element o when they form ions?
atoms gain and lose electrons, so they can have a full outer shell of 8 electrons (or two electrons if its the innermost shell) when atoms lose electrons it is called oxidation and when they gain electrons they are said to be reduced. OIL RIG is most commonly used to help remember that oxidation is loss and reduction is gain of electons. when atoms lose electrons they are left with a positive charge and when they can electrons they have a negative charge.
What is meant by gain or lose electrons?
The electrons surrounding the nucleus of an atom are in fixed 'layers' - with a defined number of electrons in each 'shell'. Stable atoms have a fixed number of electrons in their outer shell. When two atoms combine (to form a molecule) one electron is 'discarded' and the two atoms share a common electron to keep the molecule stable. The electron that's 'discarded' is said to be 'lost'. The electrons are still present - just 'free-floating'. When two atoms split, they 'grab' a free-floating electron to stabilise the molecule again. This electron is said to have been 'gained'.
