Answer:
An ionic bond forms between two ions of opposite charges. In ionic bonding, electrons transfer from one atom to another. The elements take on either a negative or positive charge. Ions are another name for charged atoms. Some elements are electropositive, and some are electronegative.

Answer:
the amount of soduim phosphate is will be 52 percemt
Answer:
An atom becomes charged when there is an unequal amount of positive and negative particles in the nucleus.
An atom gets a positive charge when there is an increase in protons or a decrease in electrons, such that there are more protons than electrons in the nucleus.
An atom gets a negative charge when there is an increase in electrons or a decrease in protons, such that there are more electrons than protons in the nucleus.
An atom can get a charge with a change of particles in the nucleus if that change results in an uneven number of protons and electrons.
Explanation:
Because protons are positively charged particles and electrons are negatively charged particles, a neutral atom has an equal amount of protons and electrons, so that the opposite charges of the particles cancel each other out.
However, if there is an unequal amount of protons or electrons in the nucleus, the charge of the particles will no longer be canceled out, and the atom as a whole will take on a positive or negative charge.
Answer:
0.43mol of Mg(OH)2
Explanation:
the molar mass of Mg(OH)2 is 58.319g/mol so you divide 25 by that and get the amount of moles.
