What else can I help you with?
Electrons that are held most loosely in an atom are called what?
The electrons in the valence band, this can be 1 to 8 electrons (in the s and p orbitals of the outer shell) depending on the element.
Is boron protons electrons or neutrons?
Boron is an atom or element, and it contains protons, electrons, and neutrons.
An element such as Magnesium Mg with two outer electrons would have a charge of?
Any atom of any element has no net electrical charge. The number of "outer" electrons is irrelevant, because the charge of all the electrons is balanced by an equal number of protons in the nucleus of the atom. However, the number of outer electrons is highly relevant to the charge of the most likely ion formed from an atom of an element by chemical reaction: Magnesium and other atoms with two outer electrons almost always form cations with 2 net positive charges when the atoms react chemically with some atom of another element, because these two outer electrons are less tightly bound to the atomic nucleus than any other electrons of the atom.
How many electrons does curium have in its outer most shell?
Curium, as an actinide element, has 4 electrons in its outermost shell (shell 7).
Choose the element that will most easily lose an electron?
Alkaline Earths will most easily lose an electron. This is because the have a smaller alkali radii than alkali metals causing them to not be as tightly bound to the nucleus. This makes the more readily lose their electrons.
Which element holds its electrons most tightly?
Fluorine holds its electrons most tightly among the elements. This is because fluorine has the highest electronegativity value on the periodic table. Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.
How many electrons are in its outermost shell?
It depends on the element in question. The outer most shell of electrons will hold the remainder of the electrons after all inward shells are filled. The first shell will only hold up to 2 electrons. After each shell holds up to 8 electrons (if the atomic number is <20).
What has scientist listed to be at the top of items that hold or give up electrons?
The most electronegative element is fluoride. The most electropositive element would be Francium however there has never been enough of it collected to perform the measurement on.
What is the number of valence electrons (number in the outer most energy level)?
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
Pick the statement that is most likely to be true of an element with LOW electronegativity?
An element with low electronegativity is likely to be a good conductor of electricity since it has a weaker ability to attract and hold on to electrons. This means that the element is less likely to form strong covalent bonds with other elements, making it more likely to easily share electrons and conduct electricity.
How many electrons can the first energy level in the electron cloud hold?
The first energy level can hold 2. The second level can hold 8. The third level can hold 18. Fourth and beyond can hold 32.
Are the valence electrons held most tightly by the atom?
Valence electrons are the electrons least tightly held by the atom and by definition are the electrons in the outermost shell of the electron and are highest in energy. They are the electrons that often contribute to an elements reactivity and in the case of Sodium, which as one valence electron in its ground state, it "gives up" its electron when it comes in contact with water.
Electrons that are held most loosely in an atom are called what?
The electrons in the valence band, this can be 1 to 8 electrons (in the s and p orbitals of the outer shell) depending on the element.
What part of an atom is involved the most in bonding?
Electrons are the most important element in atom bonding. Each element has an atomic number based on the number of electrons, and it is the was these different numbers of electrons link up to each other that determines how closely they will bond.
Is boron protons electrons or neutrons?
Boron is an atom or element, and it contains protons, electrons, and neutrons.

Does all gold in nature have electrons?
Gold has lots of electrons. All elements have electrons, but gold, a heavy element, has more than most.
