What is the net charge of a silicon atom if it gains three about. What is net charge on silicon if it gains three valance electron what is the net charge of a copper atom if it gains 2 electrons and gains three electrons, what. What is an atom (or group of atoms) that has an electric charge other than zero, and is created when an atom or group of atoms) gains or loses electrons a classmate claims that sodium gains a positive charge when it becomes an ion because it gains a proton. An atom that has lost electrons has a positive charge these atoms are now called ions, more specifically cations in general, cations are electropositive elements that hang onto their electrons very loosely.
The chlorine atom, which starts with seven valence electrons, gains a single electron and becomes a negatively charged chlorine ion: cl- this ion has the same electron configuration as the noble gas argon, and therefore this ion is chemically stable too. Solutions for chapter 2 problem 2p problem 2p: what is the net charge of a silicon atom if it gains three valence electrons 1401 step-by-step solutions solved by professors & experts. The neutral sodium atom has 11 protons and 11 electrons, which means it has 11 positive charges and 11 negative charges overall, the sodium atom is neutral, and it's represented like this: na but the sodium ion contains one more positive charge than negative charge, so it's represented like this.
In certain situations, however, the atom may lose or gain one or more electrons and acquire a net charge, becoming an ion aluminum, for instance, has an atomic number of 13, which tells us that an aluminum atom will have 13 protons. Because the bonding pair is shared, the atom that had the lone pair still has an octet, and the other atom gains two or more electrons in its valence shell for example, co 2 is a neutral molecule with 16 total valence electrons. Since a single proton contributes a charge of +16 x 10-19 coulomb to the overall charge of an atom, the total charge can be computed by multiplying the number of excess protons by +16 x 10-19 coulomb a similar process is used to determine the total charge of a negatively charged object (an object with an excess of electrons), except that the. An ion (/ ˈ aɪ ɒ n, -ə n /) is an atom or molecule that has a non-zero net electrical charge (its total number of electrons is not equal to its total number of protons) a cation is a positively-charged ion, while an anion is negatively charged.
The covalent bond atoms can combine to achieve an octet of valence electrons by sharing electrons two fluorine atoms, for example, can form a stable f 2 molecule in which each atom has an octet of valence electrons by sharing a pair of electrons. An atom's net charge is determined by comparing the number of protons and electrons that are in each atom there are three types of particles in an atom: protons, neutrons and electrons protons are positive, neutron are neutral (having no charge) and electrons are negative. When atoms (or groups of atoms) gain or lose electrons to achieve a stable valence shell (outermost electron shell) resulting in charged particles called ions if an atom gains electrons, number of negatively charged electrons exceed from the number of positively protons and hence an atom becomes negatively charged. Silicon is element 14 in the periodic table it has two electrons in its first shell, eight electrons in the second shell, and four electrons in the third shell since the electrons in the third shell are the outermost electrons, silicon has four valence electrons.
I'm trying to understand ions from what i understand, an ion is when the atom gains or loses electrons more electrons means it is negatively charged (anion. Home / study / engineering / electrical engineering / electrical engineering questions and answers / what is the net charge of a silicon atom if it gains three valence electrons question : what is the net charge of a silicon atom if it gains three valence electrons.
Valence electrons are electrons in the outermost energy level (and happen to be found only in the outermost s and p orbitals) define octet rule in compounds atoms tend to have the electron configuration of a noble gas. A)it gains electrons b) it gives up electrons c)it doesn't change its # of electrons d)calcium doesn't obey the octet rule 1s2 2s2 2p6 3s2 3p6 this preview has intentionally blurred sections sign up to view the full version. This charge is often small, because matter is made of atoms, and atoms typically have equal numbers of protons and electrons, in which case their charges cancel out, yielding a net charge of zero, thus making the atom neutral.
