An element has 2 protons 2 electrons and 2 neutrons what is the element?
helium
Which chemical element has 177 neutrons 77 protons and 77 electrons?
Atoms are defined by the number of protons in the nucleus; therefore, we can tell what element it is by the number of protons (the information about the neutrons and electrons is unnecessary). An atom with 77 protons is iridium.
What is the number of protons plus the number of electrons?
The number of protons plus the number of electrons isn't a recognized figure in chemistry. The number of protons is the atomic number of an element. The number of electrons is the same as the number of protons except when the element is an ion. An ionic compound results in one or more electrons moving from one element to another element. Although this is a simplification, it can be described as the atom gaining or losing electrons. The number of protons plus the number of neutrons is the atomic weight of an element.
What element has 2 electrons (neutral atom )?
Helium has 2 protons, 2 neutrons, and 2 electrons.
How many electrons does an element have if it has 17 protons and 18 neutrons?
i dont know, i hate chemistry it sucks! i wanna no 'if an element has 17 protons, how many electrons are there?' sorry i didnt no the answer
Is boron protons electrons or neutrons?
Boron is an atom or element, and it contains protons, electrons, and neutrons.
How many protons and neutrons and electrons does the element gold?
Neutrons - 118 Protons/electrons - 79
How many protons neutrons and electrons are in the element manganese?
Manganese has 25 protons, 25 electrons and 30 neutrons.
Is gold a proton?
Yes it does. All elements have electrons, protons, and neutrons.
What is element in building?
Protons, Neutrons, and Electrons
How many protons neutrons and electrons does si-28 have?
Silicon 28 (28Si) has 14 protons, neutrons and electrons.
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
What are the number of protons neutrons and electrons in an element?
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
How many protons neutrons and electrons are in k39?
Potassium is a s block element. It has 19 protons in a atom.
What effects the properties of an element?
neutrons, electrons, and protons
How many protons electrons and neutrons does the element called thorium?
Thorium (232Th) has 90 protons, 9o electrons and 142 neutrons.
Neutral atoms of the same element can differ in their number of what?
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
