Question

What kind of atom tends to lose one electron?

an atom with a single electron in its outermost shell

an atom with seven electrons in its outermost shell

an atom with a single electron in its innermost shell

an atom with a full outermost shell

Answer 1

Metals

Elements that readily lose electrons are all metals. Metals that normally lose one electron all form +1 ions with electron configurations we call “stable,” or “energetically favorable.” Element that are metal tend to loss electrons and became positively charged Ion called cations.

Step-by-step explanation:

Your letter answer: C

Answer 2

an atom with a single electron in its outermost shell

Step-by-step explanation:

The electron in the outermost shell of an atom has weakest bonding with the nucleus due to the relatively far distance. Since the lower attraction force can be exerted by nucleus, the single election residing in the outermost shell tends to lose and the atom become an positive charges ion.

One example of atom with single electron in its outermost shell is sodium, Na. Sodium atom can lose its single outermost shell an become positive ion Na+
