3-ethyl-2.4-dimethyl-octanoic acid
Answer: a. BaO
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here element barium is having an oxidation state of +2 called as 
cation and 
is an anion with oxidation state of -2. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral 
Answer:
15 electrones: 1S²2S²2P⁶3S²3P³. Fósforo
27 electrones: 1S²2S²2P⁶3S²3P⁶4S²3d⁷ - Cobalto.
56 electrones: 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s² - Bario
49 electrones: 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p¹ - Indio
Explanation:
Para llenar los orbitales electrónicos de los distintos átomos debemos hacer uso de la regla de llenado electrónico de Aufbau. Por ejemplo, para el átomo con 15 electrones, la configuración electrónica es:
1S²2S²2P⁶3S²3P³. 2+2+6+2+3 = 15 electrones
Si elemento es neutro, tiene 15 protones. Es decir, es el fósforo, P.
27 electrones:
1S²2S²2P⁶3S²3P⁶4S²3d⁷ - Cobalto.
56 electrones:
1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s² - Bario
49 electrones:
1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p¹ - Indio
