When an atom undergoes beta decay, wich of the following is true?

 The atomic number increases by one and the element becomes a different element. 

I’m guessing you’re more alert to yourself or your surroundings if you’re more concentrated

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
