Answer:
Mira la explicación.
Explanation:
¡Hola!
En este caso, podemos encontrar facilmente el grupo al que pertenecen dichos elementos con números atómicos 8, 36 y 39 respectivamente mediante su búsqueda en la tabla periódica. Así, z=8 corresponde a oxígeno, z=36 a kriptón y z=39 a itrio.
Por otro lado, para saber el número de capas, debemos desarrollar la configuración electrónica para cada uno:
Con esto, vemos que oxígeno tiene dos capas, kripton cuatro capas e iritrio cinco, a lo que a oxígeno le faltan dos electrones para llenar dicha capa, a kripton ninguno y a iritrio nueve.
Saludos.
Atoms are made up of protons , electrons and neutrons ..,, Atoms of the same element with different number of neutrons are called isotopes. Saying that substance “contains only one type of atom “ really means that it contains only atoms that all have the same number of protons .
Answer: 0, 32 , 273
Explanation:
The freezing point of water in degree Celsius, Fahrenheit and Kelvin are in the following order; 0 , 32 , 273
To solve this problem, let us first understand what does
mega meters mean. Now by definition, mega means a factor of one million which
is a unit prefix in Metric Systems of units. It is denoted by the unit symbol
M.
So for example if we have a mega of something, it means a
million of something. So in this case, if we have 1 mega meter, what it means
is 1 million meter, which is written as:
1 mega meter = 1,000,000 meter
To show the decimal points:
1.0 mega meter = 1,000,000.0 meter
So we see that the decimal point move 6 zeroes to the
right, therefore the direction is to the right.
