Increases from left to right across a period

<h2>Answer with Explanation</h2>

The positively charged particles in the nucleus pull the negatively charged electrons. When we move from left to right, the number of protons increases then more protons attract negative charges, so electronegativity increases. This happens due to a greater charge on the nucleus which makes electron bonding pairs to be very attracted to atoms located more right on the periodic table. Fluorine is the most electronegative element which is present in seventh group known as halogen group.

Ter the symbol for the isotope used in blood flow analyses.
blondinia [14]

Answer:

The symbol of isotopes used for blood flow analysis is \begin{array}{c}{141} \\ {58}\end{array} C e.

<u>Explanation: </u>

  • Isotopes are the substances that exhibit the same atomic number but has a different mass number of an element.
  • The atomic number explains the number of protons present in the element and mass number explains the number of neutrons available in the element.
  • For blood flow analysis, the isotope element is cerium-141 and it is used in the chemical examination of blood flow particles.
  • Symbol used for this isotope is \begin{array}{c}{141} \\ {58}\end{array} C e, where 141 indicates the amount of mass present and 58 indicates the proton number and 83 indicates neutron number present in that element.
  • The amount of mass in an atom is calculated by the sum of protons and neutrons present in it. Thus mass of isotope is 141 obtained by the sum of 58 protons and 83 neutrons present in that isotope.

mezya [45]

Answer:

See explanation

Explanation:

The law of conservation of mass states that mass can neither be created nor destroyed. This implies that in a chemical reaction, we can only have the same number of atoms of each element on both sides of the reaction equation.

If we write  4Fe2S3 it means that we have;

4 * 2 = 8 atoms of Fe

4 * 3 = 12 atoms of S

8 + 12 = 20 atoms in all
