Answer:
in the excited state
Explanation:
Because in excited state an atom has more energy
<span>The region(s) of the periodic table which are
made up of elements that can adopt both positive and negative oxidation numbers
are the “non-metal” region. As we can see on the periodic table, the elements situated
at the right side of the table have two oxidation states, one positive and the
other a negative. </span>
Answer:
The physical properties of matter are any properties that can be perceived or observed without changing the chemical identity of the sample. In contrast, chemical properties are those that can only be observed and measured by performing a chemical reaction, thus changing the molecular structure of the sample. Mass (like volume) is an extensive physical property because its value depends on the quantity of the matter, unlike temperature. It is not a chemical property as its measurement includes no chemical reaction and change.
Hope this helps!
The atomic number of an atom is the amount of protons.
So this atom has 26 protons and the amount of protons are EQUAL TO THE AMOUNT OF ELECTRONS.
So this atom has 26 electrons.
