Atomic mass = 39
number of neutrons = 20
Number of protons= 19
Electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1
The number of electron in first shell = 2
number of electrons in n=3 shell = 8
Explanation:
An oxidation number is a number that is assigned to an atom in a substance. The oxidation number could be positive, negative, or zero, and it indicates if electrons are lost or gained. In other words, the oxidation number is a number that helps us keep track of electrons in an atom.
Answer: O D. A digital signal moves between a discrete number of values.
Explanation:
The digital signals are considered more reliable over the analog signals as they encode the information in a coded form. The bits or samples of the data are transmitted and converted into digital and numerical value. The stream of encoded data is in the form of continuous data at regular time intervals. It provides information in waveform and the data is in compact form. The data is in the form of binary bits 0 and 1 so greater the number of bits greater will be the greater will be the resolution of the information.
Adding salt increases the boiling point of the water, which would make it so the water takes longer to get to a boiling point.
