How does an atom become a positive ion?

Biology
2 answers:
solong [7]3 years ago

An atom that gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion. Some atoms lose electrons and become positive ions. Others gain electrons and become negative ions.

<h2>Answer: </h2>

An atom becomes a positive ion by losing one or more of its electrons. Positively charged ions are called cations.

Positively charged ions are called cations. Generally, metallic elements turn into positive ions due to the quantity of valence electrons they contain. Metallic ions can achieve a full valence shell if they lose their outer electron(s). When they lose these electrons, the inner shell is now their valence shell, and it's complete. When this happens, they will have more protons than electrons, giving the atom a positive charge.

A human chromosome is what?

Long DNA sequences are carried by chromosomes, structures that are found in the cell nucleus. The substance that contains genes is called DNA. It serves as the foundation for the human. Additionally, the proper DNA structure is aided by the proteins contained in chromosomes.

What do the chromosomes of the gender do?

When you are born, your X and Y chromosomal determine whether you are a boy or a girl. Gender chromosomes, as they are known, are actually called X and Y chromosomes in females. Men possess simply a X and a Y.

1. List and explain the difference between the minimum voltage and maximum voltage achieve in a nerve impulse
algol [13]
The normal membrane potential inside the axon of nerve cells is –70mV, and since this potential can change in nerve cells it is called the resting potential. When a stimulus is applied a brief reversal of the membrane potential, lasting about a millisecond, occurs. This brief reversal is called the action potential 
<span>A stimulus can cause the membrane potential to change a little. The voltage-gated ion channels can detect this change, and when the potential reaches –30mV the sodium channels open for 0.5ms. The causes sodium ions to rush in, making the inside of the cell more positive. This phase is referred to as a depolarisation since the normal voltage polarity (negative inside) is reversed (becomes positive inside). </span>

<span>Repolarisation. At a certain point, the depolarisation of the membrane causes the sodium channels to close. As a result the potassium channels open for 0.5ms, causing potassium ions to rush out, making the inside more negative again. Since this restores the original polarity, it is called repolarisation. As the polarity becomes restored, there is a slight ‘overshoot’ in the movement of potassium ions (called hyperpolarisation). The resting membrane potential is restored by the Na+K+ATPase pump.</span>
