Question

Most elements, with the exception of a few like hydrogen, want to have _________ electrons in the outer energy level.

Answer 1

Answer: two electrons

Step-by-step explanation:

Most elements, with the exception of a few like hydrogen, want to have ___two______ electrons in the outer energy level.

Hydrogen has an atomic number 1 that is to say a proton and an electron, hydrogen due to deficiency in electrons and other elements in group 1 that obey the octet configuration will need two electrons in the outer energy level ad thus since it has one and will still need one extra making two electrons so that the outer energy can achieve stability.

Answer 2

The answer is 1.

Most elements, with the exception of a few like hydrogen, want to have 1 electrons in the outer energy level.

Hydrogen has 1 electron in its outer shell, it requires two electrons to be in stable state. It can hold upto, two electrons in it's outer shell.
