Answer:
You could trip down and fall with your phone in your hand, however by accident you may throw your phone before hitting the ground to crack it and when you throw the phone, you could have directly thrown it at the tv and then the phone bounced off the tv caused by impact and hit the ground harshly causing the phone and tv to crack or break in the process and to add you might be also, hurt from the fall. Hope this helps :)
2. F is non-metal, because it has seven electrons (more that 3)
3.It <span>fills its shell by gaining one electron, because it is easier to gain 1 e⁻ than to loose 7 e⁻.
4. It </span><span>becomes a negatively charged ion, because atom of F is neutral, it has "0" charge, and it takes one negatively charged electron(-1). (0 +(-1)= -1)</span>
Answer:
Have the same number of electrons in their outer energy levels
Explanation:
Elements in the same group have similar chemical properties because they have the same number of valence electron(s) in their outermost shell.
Chlorine and Iodine have similar chemical properties because they have the same number of valence electron in their outermost shell. This can be seen from their electronic configuration as shown below:
Cl (17) => 1s² 2s²2p⁶ 3s²3p⁵
I (53) => [Kr] 4d¹⁰ 5s²5p⁵
From the above illustration:
Outer shell of Cl (3s²3p⁵) = 2 + 5 = 7 electrons
Outer shell of I (5s²5p⁵) = 2 + 5 = 7 electrons
Since they have the same number of valence electrons, therefore, they will have similar chemical properties.
They might change because of the flies color
Answer:
D. Provides higher resolution images
Explanation:
The advantages gained by the use of digital data transmission instead of analog transmission are;
1) Noise do not damage digital signal transmission but they impact on analog signals. Digital signals are therefore more secure than analog signals
2) The bandwidth required for digital signal transmission is much less than the bandwidth required for analog
3) Digital signal allow data transmission to very long distance
4) The rate of transmission with digital signals is higher with digital signals
5) Digital signals allow easy and cost effective methods by which they are replicated
The resolution of an image is a measure of the amount of pixels displayed per inch of the image, such that a high resolution image has more pixel per inch of the image. It is therefore a factor determined at the source of the image based on how much detail is required in an image before transmission
