Answer:

1 positively charged sodium ion

2 sodium ion that has lost an electron

Explanation:

Sodium is represented by the symbol Na. It has an atomic number of 11. In neutral state, it has 11 protons and 11 electrons. The electron shells are filled in the order 2,8,1. Thus, one electron remains in the outermost shell. To achieve stable state, Na loses one electron. The result is the formation of sodium ion which has one positive charge and which denotes the loss of one electron.

OPTIONS:

a. When there are just two other people at the party.

b. When everyone is wearing a nametag.

c. When there are more than 50 people attending the same party.

d. When the need for help from the person who is having a heart attack is very clear

Answer:

c. When there are more than 50 people attending the same party.

Explanation:

Bystander effect is a term used in social psychology to describe the tendency of an individual to intervene in the event of an emergency to offer help to the person needing it, when others are present at the scene of the emergency.

In the case of an emergency just like the scenario stated in the question, where someone develops a heart attack at a dance party, if the party has more people, the slimmer the chance of the person getting help from any of the 50 people at the party, as the presence of others would tend to discourage the any individual from attempting to help the victim having the heart attack.

The situation that would more likely show the bystander intervention effect is <em>"c. When there are more than 50 people attending the same party."</em>

What technology is allowing astronomers to study these phenomena such as star explosions, neutron stars, and black holes
Vanyuwa [196]

Phenomena such as star explosions, neutron stars, black holes etc. are studied with the help of extremely powerful and sensitive telescopes.

These sophisticated instruments are able to see more than our own eyes can. Thus, they detect wavelengths outside of those found in our visible spectrum, such as X-rays etc.

The most sophisticated telescopes are those that are placed in space such as the Hubble or Spitzer Space Telescope. In this way, these instruments are able to circumvent the Earth's atmosphere that may block the view of the sky. Thus, in space, they have the optimal conditions to observe and study in detail such phenomena.
