What is the best describe of electron?

An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron.

How do you describe electrons?

electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton.

Which statement best describes the electrons in the illustration?

Which statement best describes the electrons in this illustration? The electrons are negatively charged particles located outside the nucleus.

Which statement best describes how electrons fill orbitals in the periodic table?

Which statement best describes how electrons fill orbitals in the periodic table? Electrons fill orbitals in order of their increasing energy from left to right.

What are three characteristics of electrons?

What are the Characteristics of Electron, Proton and Neutron

S.no	Electron	Proton
(ii) Nature	Negatively charge	Positively charge
(iii) Relative mass	1/1840 of a H atom	equal to H atom
(iv) Actual mass	9.1 × 10–28 g	1.67 × 10–24 g
(v) Charge	(– 1) (1.602 ×10–19 C)	(+ 1) (1.602 × 10–19 C)

Which statement best describes how protons are held together in the nucleus of stable atoms?

A strong nuclear force between an atom’s protons and neutrons holds together the atom’s nucleus. Protons experience a more powerful attraction to the negatively charged particles in an atom’s nucleus. A strong nuclear force between an atom’s protons and neutrons holds together the atom’s nucleus.

Can electrons be positive?

Electrons. Proton—positive; electron—negative; neutron—no charge. The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another in a neutral atom.

Which elements absorb the most energy by gaining an electron?

The elements of which group in the periodic table release the most energy by gaining an electron – Group 7A (one away from being full) The elements of which group in the periodic table absorb energy when gaining an electron – Group 8A, the noble gasses because they have high electron affinity.

What element has the greatest ability to attract electrons?

Electronegativity is a measure of the ability of an atom to attract electrons. The greater the ability to attract, the higher the electronegativity. Chlorine has the highest electronegativity of the choices given.

Which elements are most likely to lose electrons?

Alkaline earth metals, the elements in the second column of the periodic table, are the most likely elements to lose two electrons in chemical reactions.

Which statement about electrons is true?

The statement that is true about a proton and an electron would be that they have different masses and different charges. Protons and neutrons have nearly the same mass while electrons are much less massive.
