Valence electrons are the highest energy electrons in an atom and are therefore the most … ct kids abducted to lebanonWebIt is most likely to. Q: ANSWER QUICKLY pls 1.The Lewis dot model of a metal atom has two dots. Which of the following is true about the atom? It. Q: . If atom A loses electrons to atom B, a. how many electrons will atom A lose? b. how many electrons will atom B gain? c. Q: Your chemistry teacher writes the following on the board " Na+ ". ct kids agencyWebThis one can hold 2 electrons. Once you get to the third electron, you have to put it in the next orbital. This one is called the 2S orbital. (All "S" orbitals hold 2 electrons.) Next comes the 2P shell. "P" orbitals hold 6 electrons. After 2P is 3S, 3P, 4S, 3D, 4P, etc. ("D" orbitals hold 10 electrons each.) earth organics formulaWebMost of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. Some atoms can be stable with an octet even though their valence shell is the 3n shell, which can hold up to … A helium atom has two protons in the nucleus and a typical helium atom would … Valence electrons are the electrons in the outermost shell, or energy level, of an … earth organics shoes for womenWebThe 3+ charge indicates that the element has lost 3 electrons. So, if the cation has 10 electrons, the neutral atom must have had 13 electrons because losing 3 of those results in a charge of 3+. And from here, we know that the element has 13 protons because the number of protons is equal to the number of electrons in a neutral atom. ct kids killed in crash
