What kind of atom tends to lose one electron?

Biology
2 answers:
Romashka-Z-Leto [24]3 years ago
4 0

Answer:

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.

Explanation:

Your letter answer: C

Answer:

an atom with a single electron in its outermost shell

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+

How will you investigate a change in velocity affects the velocity of the two carts after the collision if the objects do not st
Nutka1998 [239]

P = mv

This is a momentum question:

Momentum is always conserved so the momentum before and after a collision must be equal so:

The velocity of the two objects after they collide and dont stick together if no KE is lost is dependent on the mass of each of the objects by:

m_{1} v_{1i} + m_{2} v_{2i} = m_{1} v_{1f} + m_{2} v_{2f}\\

Where i is initial and f is final meaning before and after the collision

The shape of a protein is primarily determined by
bulgar [2K]


The best answer is A.

The shape of a protein is determined by its primary structure. The primary structure is the sequence of amino acids  in each polypeptide chain which make up a protein.

The sequence of amino acids is basically a list of amino acids that are linked to each other to form a chain which is known as a polypeptide chain.

The structure of the finished protein will depend largely on the first  (primary) chain of amino acids to be produced to make up that protein.

The volume and mass of the brain has increased about threefold from early human ancestors such as Australopithecus afarensis, to
spin [16.1K]

The question is incomplete as it does not have the options which are:

A. The threefold change happened in one concentrated burst.

B. The change was not consistent in direction, but happened in multiple bursts concentrated at each speciation event.

C. There was consistent directional selection toward a larger brain all along the lineage between the two species.

D. None of the above.

Answer:

Option-B

Explanation:

The hominids evolved with time and the known hominid in modern time is the Homo sapiens or modern human.

The Homo sapiens like other species could have evolved from the older species through speciation and studies suggest that one of the major factors of human evolution is the size of the brain.

Two possibilities could explain the size of the brain that it could have evolved slowly with time called the gradual equilibrium or in bursts concentrated at each speciation event.

Since the punctuated equilibrium takes place in bursts until the species reach stasis is the most applicable condition for punctuated equilibrium to happen therefore Option-B is the correct answer.
