A. how do you determine the charge of an element?
NemiM [27]

Answer:

Explanation:

A. The charge on an element is determined by the differences between the number of protons and electrons in an atom.

An atom will have no charges if the number of protons and electrons are the same.

  • When an atom loses or gains electrons, the number of electrons will either decrease or increase
  • if the number of electrons is more than the number of protons, the excess electrons is the charge on the atom. And this makes the atom become a negatively charged ion.
  • if the number of electrons is lesser than the number of protons, the deficient electrons makes the atom a positively charged ion. The number of electrons by which the atom is deficient makes the atom a positively charged ion.

Charge  = number of protons  - number of electrons

B. Electrons form the charges they do because with the charge, they become stable like the noble gases.

The desire of every atom is  to have stable electronic configuration like those of the noble gases.

A potassium atom with a configuration 2 8 8 1 will prefer to lose an electron to become an Argon atom making the ion stable.

The Difference Between an Alloy and an Amalgam
Delicious77 [7]

Mixtures or combinations of various different metals or metallic substances form things called alloys. An alloy composed of mercury and other metal (or metals) forms "amalgam". When a true alloy is created, the component metals are combined together at a temperature which is greater than the melting point of all of them.

Also, it helps to remember the word "amalgamate", which means "to alloy (a metal) with mercury" according to Dictionary.com.


Hope this helped :)

A substance that does not allow x-rays to pass through is described as being
horsena [70]

A substance that is impenetrable by x-rays is described as being radiopaque.

Radiopaque substances will not allow x-rays and or other forms of radiations to pass through them.

Instead, they absorb or block the rays and when used in radiology, they appear white or light gray on photographic films.

Radiopaque materials are applied in generating ultrasound images and other forms of clinical procedures.

Estimate the pH of the resulting solution if you mixed equal amounts of hydrochloric acid (HCI) and sodium hydroxide (NaOH).
ioda
It obtains a neutral pH (7). The combination of a strong acid and a strong base results in a neutral pH. The pH of HCl is about 1, and the pH of NaOH is 14.
