Electrons
A negatively charged atom is a electron.
Its outer shell electrons. In ionic bonding, an atom loses one or more of its outer shell electrons (making it a positively charged ion) to the outer shell of another atom; making this a negatively charged ion.
To rearrange its configuration to result in a complete outer shell
It is the nucleus of an atom that is positively charged. You'll recall that an atom is made up of protons, neutrons and electrons (hydrogen-1 excepted). And the protons and neutrons hang out in the nucleus, giving it an overall positive charge because the proton has a positive change.
Because atoms like to have a full outer shell - a sodium (1+) ion previously had 1 electron in it's outer shell, but it loses a (negatively charged) electron to gain a +1 charge. Chlorine, however, usually has 7 electrons in it's outer shell, but it gains a (negatively charged) electron to gain a -1 charge. Remember; gaining electrons = negative ions losing electrons=positive ions
The negatively charged particles of an atom are in an outer shell.
A negatively charged atom is a electron.
Electrons
It is called an electron. An electron is one of the subatomic particles in an atom. A proton has a positive charge. A neutron has a negative charge. An electron has a negative charge. The electron floats around the nucleus of the atom in the electron cloud. The nucleus is made up of protons and electrons.
No! Electrons are negatively charged. A neutral atom gaining a electron will, by necessity, become negatively charged. Cl(-)
Those would be the electrons (found "orbiting" the atomic nucleus). Chemical reactions normally involve transfer or sharing of the "outer shell" electrons.
Scientists believe it is the outer core, the inner core is solid. Electricity moving through wires cause magnetic fields. Charged particles stuck in the liquid core moving around mimic charged electrons in an electric current.
Its outer shell electrons. In ionic bonding, an atom loses one or more of its outer shell electrons (making it a positively charged ion) to the outer shell of another atom; making this a negatively charged ion.
Ions are formed when atoms gain or lose electrons in their outer orbit/shell. Electrons are negatively charged so if they lose an electron they become positively (plus) charged.
Electrons are negatively charged. (The positron is a positively charged version). Protons are positively charged, so an anti-proton would carry a negative charge. Any object that has, on average surplus electrons in the outer-shells of electron orbitals will appear negatively charged.
To rearrange its configuration to result in a complete outer shell
A chlorine requires one more valence electron to achieve a full outer shell; thus, it is negatively charged - an anion.
