Your answer is 4 protons 4 electrons and 5 neutrons
The bond length and energy of the bond formed between hydrogen (H) and astatine (At) would change if the bond order <u>increases</u> or <u>decreases</u> or when its potential energy is at the <u>lowest</u>.
<h3>What is bond length?</h3>
Bond length is also referred to as bond distance and it can be defined as an equilibrium distance between the nuclei of two (2) covalently bonded atoms in a molecule.
<h3>What is bond energy?</h3>
Bond energy can be defined as the amount of chemical energy that is required to break one mole of a given chemical bond.
In Chemistry, the bond length and energy of a molecule is typically determined by the following:
- The bond order or number of bonded electrons.
- The potential energy possessed by the molecule.
In conclusion, you can predict that the bond length and energy of the bond formed between hydrogen (H) and astatine (At) would change if the bond order increases or decreases or when its potential energy is at the lowest.

The part of the atom that accounts for electricity is the electron. As it also determines the properties.
Answer: Electrons
Answer:
The mass of nickel is 48μg
Explanation:
Parts per billion is a way to describe small concentrations and is defined as the ratio between μg of solute and kg of solvent.
If a solution of nickel in propanol is 20ppb, contains 20μg of nickel in 1 kg of propanol.
Thus, a sample of 2.4kg of propanol will contain:
2.4kg × (20μg nickel / 1kg) = 48μg nickel
<h3>The mass of nickel is 48μg</h3>
Answer:
C a chemical has become a different color
Explanation:
is it a chemical change when water turns to ice? or to water vapor? no because it can easily change back.
it's not A obviously
I just explained why it's not B
and again it's obviously not D
It's C because once you change the color of something you can most likely not change it back (cake batter, stained glass) making it a chemical change
