1s^2 2s^2 <span>is the electron configuration for an electrically neutral atom of beryllium(Be).</span>
Answer:
B: All of the choices!
Explanation:
Choice 1: Simply, there is no current without voltage, so it DOES cause current.
Choice 3: Voltage DOES push free electrons around a circuit. Without it, free electrons will move around between atoms, but randomly, so they wouldn't be much use.
Choice 4: Voltage IS measured in volts, so this option is true as well.
Choice 2: Voltage is all of those answers, so it is true! :D
Hope i helped! :]
There are 115 protons in the element 115 and due to the large number of protons, the element does not exist in nature.
Also, the element can not be isolated in nature that is IUPAC had to require an independent confirmation of the element.
<h3>What is element 115?</h3>
We know that the periodic table is an arrangement of the atoms in order of increasing atomic number. We know that the larger the atomic number of the element, the less likely that the element would be stable in nature. The element that have been named 115 is called Moscovium and was discovered in Moscow as a product of a radioactive experiment. The number of protons in element 115 is 115 protons
Generally, the element number 115 does not exist in nature because if the proton number in an element exceeds 82, the repulsion between the protons would make it almost impossible for the nucleus to be a stable nucleus.
The reason why IUPAC had to request an independent confirmation of the element is because it does not exist in nature.
