Answer:

The halogens located in group 17

Explanation:

The change in energy of a neutral atom when an electron is added is known as electron affinity. <em>Fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At) are known as halogens and conform the group 17 of the periodic table, the group that presents higher electron affinity.</em> This characteristic happens because of their atomic structures, it is easier for them to gain electrons because they are closer to form octets.

Here I present you halogens' electron affinities values:

  • Fluorine (F) -328 kJ mol-1
  • Chlorine (Cl) -349 kJ mol-1
  • Bromine (Br) -324 kJ mol-1
  • Iodine (I) -295 kJ mol-1

<em>The use of negative signs is to indicate the RELEASE of energy.</em>

I hope you find this information useful and interesting! Good luck!

Find a total pressure of the gas mixture that contains forecast is with partial pressure of 5.00 kPa, 4.56 kPa 356 kPa and 678KP
Orlov [11]

Answer: 1044 kPa

Explanation: To find the total pressure of a system, you add up all the partial pressures. 5.00+4.56+356+678=1043.56, but since you need to account for significant figures it is 1044.

In addition, the amount of significant figures is the number with the smallest amount of decimal places. In this case you have no decimal places, since 356 and 678 have no decimal places. Remember that for the numbers 0-4 you round down and 5-9 you round up.

Hydrogen (H) and helium (He) are produced in the core of stars in a process called nuclear fusion. Over time stars begin to prod
rosijanka [135]
A C and D are all correct, Helium and Hydrogen only have a 1s orbital, and helium has 2 protons, while hydrogen has 1, and finally Hydrogen has no neutrons while helium has 2. Helium does not however have 8 valence electrons as the 1s orbital can only hold 2, meaning B is the “correct” (false) answer.

<h3><u>Answer;</u></h3>

10 percent

<h3><u>Explanation;</u></h3>
  • Probability is a number that describes how likely it is that an event will occur.
  • In this case; If each of 10 events is equally likely to occur, the probability of each individual event occurring is 1/10.
  • Therefore; as a percentage;

1/10 × 100 = 10 percent

  • Hence; The probability of each individual event occurring is 10 percent
